    Rate this question:

  • 4. 

    If 4(3x - 3) = 24, what is 5x - 5?

    • A.

      10

    • B.

      6

    • C.

      24

    • D.

      3

    • E.

      4

    Correct Answer
    A. 10
    Explanation
    To solve the equation 4(3x - 3) = 24, we first distribute the 4 to the terms inside the parentheses: 12x - 12 = 24. Then, we isolate the variable by adding 12 to both sides of the equation: 12x = 36. Finally, we solve for x by dividing both sides of the equation by 12: x = 3.
    To find 5x - 5, we substitute the value of x into the equation: 5(3) - 5 = 15 - 5 = 10. Therefore, the answer is 10.

    Rate this question:

  • 5. 

    The average of 11 numbers is 21 . The average of seven of those numbers is 25. What is the average of the remaining four numbers?

    • A.

      4

    • B.

      12

    • C.

      14

    • D.

      21

    • E.

      25

    Correct Answer
    C. 14
    Explanation
    The average of the 11 numbers is given as 21. This means that the sum of all the 11 numbers is 11 multiplied by 21, which is 231. The average of the seven numbers is given as 25, which means the sum of those seven numbers is 7 multiplied by 25, which is 175. To find the sum of the remaining four numbers, we subtract the sum of the seven numbers (175) from the sum of all 11 numbers (231). This gives us 56 as the sum of the remaining four numbers. To find the average of these four numbers, we divide the sum (56) by the count (4), which gives us an average of 14.

    Rate this question:

  • 6. 

    Which of the following is equivalent to 6x 2 + x - 12 ?

    • A.

      (2x + 3)(3x - 4)

    • B.

      (2x - 3)(3x - 4)

    • C.

      (2x + 3)(3x + 4)

    • D.

      (6x + 3)(x - 12)

    • E.

      (x + 3)(2x - 12)

    Correct Answer
    A. (2x + 3)(3x - 4)
    Explanation
    The given expression is 6x^2 + x - 12. The correct answer, (2x + 3)(3x - 4), can be obtained by using the distributive property to multiply the two binomials. When we multiply (2x + 3) with (3x - 4), we get 6x^2 - 8x + 9x - 12, which simplifies to 6x^2 + x - 12. Therefore, (2x + 3)(3x - 4) is equivalent to the given expression.

    Rate this question:

  • 7. 

    • A.

      81

    • B.

      40

    • C.

      72

    • D.

      9

    • E.

      18

    Correct Answer
    C. 72
    Explanation
    The given sequence of numbers is 81, 40, 72, 9, 18. If we observe closely, we can see that each number is obtained by multiplying the previous number by a certain factor. In this case, the factor is 0.5. Starting with 81, we multiply it by 0.5 to get 40.5, which is rounded down to 40. Then, we multiply 40 by 0.5 to get 20, and so on. Therefore, the next number in the sequence would be obtained by multiplying 18 by 0.5, giving us 9. Finally, multiplying 9 by 0.5 gives us 4.5, which is rounded up to 5. However, since 5 is not given as an option, the correct answer is 72, which breaks the pattern and does not follow the multiplying factor.

  • 8. 

    If 2 dots are equal to 3 dashes and 5 dashes equal to 7 stars, what is the ratio of one dot to one star?

    • A.

      10 ⁄ 21

    • B.

      3 ⁄ 5

    • C.

      5 ⁄ 3

    • D.

      21 ⁄ 10

    • E.

      2 ⁄ 3

    Correct Answer
    D. 21 ⁄ 10
    Explanation
    According to the given information, 2 dots are equal to 3 dashes and 5 dashes are equal to 7 stars. To find the ratio of one dot to one star, we need to find a common factor between dots and stars. We can do this by finding a common factor between dots and dashes, and then between dashes and stars. The common factor between dots and dashes is 3, and the common factor between dashes and stars is 5. Therefore, the ratio of one dot to one star is 3/5. Simplifying this ratio gives us 21/10.

    A social welfare organization spends 40% of the funds collected towards old-age homes. If during an year 1.6 million dollars was spent on old-age homes, what is the total amount of funds collected in millions of dollars?

    • A.

      4.0

    • B.

      6.0

    • C.

      4.6

    • D.

      40.0

    • E.

      1.6

    Correct Answer
    A. 4.0
    Explanation
    Option A is correct.
    Let the total fund = n million dollars
    40% of n = 1.6 million dollars
    Or 0.4n = 1.6 million dollars
    Or n = 1.6/0.4 million dollars = 4 million dollars
    Hence 40% of 4 is 1.6
    B is not correct, as 40% of 6 is 2.4 and not 1.6
    C is not correct, as 40% of 4.6 is 1.84 and not 1.6
    D is not correct, as 40% of 40 is 16 and not 1.6
    E is not correct, as 40% of 1.6 is 0.64 and not 1.6

    • E.

      160 degrees

    Correct Answer
    C. 100 degrees
    Explanation
    As other angle measures are not equal to the calculated measure of ∠ABC, only
    option C is correct.
    Exterlor angle of a tr|angle |s equal to the sum of its two interior opposite angles.
    ∠ABD = ∠BDC - ∠BAD = 60° - 30° = 30°
    ∠CBD = ∠BCE - ∠BDC = 130° - 60° = 70°
    ∠ABC = ∠ABD + ∠CBD = 30° + 70° = 100°

    • B.

      25.5

    • C.

      42.5

    • D.

      13

    • E.

      50

    Correct Answer
    B. 25.5
    Explanation
    As other speeds given are not equal to the calculated average speed only option B is correct.
    Speed = distance traveled/time taken
    Total distance traveled = (250 +700 + 325) mile = 1275 miles
    Time = distance/speed
    Total time = (250/50 + 700/35 + 325/13) hrs = (5 + 20 + 25) hrs = 50 hrs
    Average speed of the car = 1275/50 miles / hr = 25.5 miles/hr

    • C.

      5

    • D.

      8

    • E.

      11

    Correct Answer
    D. 8
    Explanation
    Option A is not correct is not correct. 98765432 is not divisible by 9 as the sum of its digits 44 is not divisible by 9.
    Option B is not correct as 98765432 is not divisible by 7.
    Option C is not correct as the last digit of 98765432 is not 5, hence 98765432 is not divisible by 5.
    Option D is correct. Using the tests of divisibility, we know that a number is divisible by 8 if its last three digits are divisible by 8. The last three digits of the given number 432 is divisible by 8.
    Option E is not correct. As the difference of the sum of digits in its even and odd places {(9 + 7 + 5 + 3) - (8 + 6 + 4 + 2)} 4 is not a multiple of 11, 98765432 is not divisible by 11.

    • D.

      30

    • E.

      4

    Correct Answer
    E. 4
    Explanation
    Number of students in the class = n(T∪C) = 30
    Number of students who take tea = n(T) = 14
    Number of students who take coffee = n(C) =20
    Number of students who take both tea and coffee = n(T∩C)
    n(T∩C) = n(T) + n(C) - n(T∪C)
    =14 + 20 - 30 = 34 - 30 = 4

    • D.

      20 square units

    • E.

      15 square units

    Correct Answer
    D. 20 square units
    Explanation
    As other areas given are not equal to the calculated area, only option D is correct.
    Area of square ABED = 9 square units or side of square ABDE
    BE = side of square ABED = 3 units
    EF = 1 unit.
    Width of the rectangle BCGF= BF = BE + EF
    = 3 units + 1 unit = 4 units
    Length of the rectangle BCGF= BC = 5 units
    Area of the rectangle BCGF = 1 * w
    = 5 * 4 square units
    = 20 square units

    Each month for 6 months the price of a commodity is doubled. At the end of the 6 months the price of the commodity is $640. What was the price of the commodity at the end of 3 months?

    • A.

      $100

    • B.

      $120

    • C.

      $80

    • D.

      $320

    • E.

      $160

    Correct Answer
    C. $80
    Explanation
    The price of the commodity doubles each month for 6 months, so we can find the original price by dividing the final price by 2 raised to the power of the number of months (6). $640 divided by 2 raised to the power of 6 is $640 divided by 64, which equals $10. Therefore, the price of the commodity at the end of 3 months would be $10 divided by 2 raised to the power of 3 (since 3 months is half of 6 months), which equals $10 divided by 8, or $1.25. However, none of the given options match this calculation, so the correct answer cannot be determined.

    • D.

      D. x < 0 and y > 0

    • E.

      E. x > 0 and y > 0

    Correct Answer
    D. D. x < 0 and y > 0
    Explanation
    Option A cannot be chosen, if x = 0 then both the inequalities given will be zero which is not true.
    Option B be cannot be chosen, if y = 0 then both the inequalities given will be zero which is not true.
    Option C cannot be chosen, if x > 0 and y < 0, then x2y will be less than 0 as the product of a positive number and a negative number will be negative. Similarly xy2 will be positive, which is not true.
    Option D is correct. If x2y n> 0, then x2 is anyway positive, hence y must also be positive so that the product is positive. If xy2 < 0, then y2 is anyway positive, hence x must be negative so that the product is negative. Hence x < 0 and y > 0.
    Option E cannot be correct. If both x and y are positive, then only x2y > 0 will be true and xy2 will be false.

    • E.

      E. 14:11

    Correct Answer
    E. E. 14:11
    Explanation
    Only option E is correct as the other ratios given do not satisfy the relation
    Radius = 21units
    Circumference = 2πr = 2 * 22/7 *21 units = 132 units
    Circumference of the circle = perimeter of the square or
    4a = 132 units or a = 33 units
    Therefore, side of the square is 33 units
    Area of circle: Area of square = πr2:a^2
    = 22/7 *21*21: 33*33
    =14:11

    Explanation
    Option A is not correct as f(3x+3 / x-1) ≠ x+1
    Option B is correct as
    f(3x+3 / x-1) = (3x+3 / x-1 + 3) / (3x+3 / x-1 - 3)
    = (3x+3+3x-3) / (3x+3-3x+3)
    = 6x/6 = x
    Option C is not correct as f(3x+3 / x-1) ≠ x-1

    Rate this question:

  • 29. 

    A jar contains 10 red marbles and 30 green ones. How many red marbles must be added to the jar so that 60% of the marbles will be red?

    • A.

      A. 30

    • B.

      B. 25

    • C.

      C. 35

    • D.

      D. 27

    • E.

      E. 125

    Correct Answer
    C. C. 35
    Explanation
    Number of red marbles in the jar = 10+x
    Total number of marbles in the jar = 10+x+30 = 40+x
    According to the problem,
    10+x/40+x = 10(10+x) = 6(40 + x)
    Or 100 + 10x = 240 + 6x or 4x =140 or x = 35
    Hence, 35 red marbles must be added to the jar.

    Correct Answer
    E. E. 130
    Explanation
    Let 0 be the center of the circle, then ∠QOR is the angle subtended by the arc QR

    The angle subtended by an arc at the center of a circle is double the angle subtended
    by the same arc on the remaining part of the circle

    Therefore, ∠QOR = 2 * 65 degrees = 130 degrees

    • E.

      E. 0.167

    Correct Answer
    E. E. 0.167
    Explanation
    Sometimes in some problems, some extra information is given, which is not required to solve the problem. Here, it is clear that the number of mangoes C got is 12.
    Total 72 mangoes minus 60 mangoes given to A and B. Hence, Fraction of mangoes C got out of the total number of mangoes
    = 12/72 = 1/6 = 0.16666. , this can be rounded to 0.167

      Insalubrious

    • E.

      Aromatic

    Correct Answer
    A. Invigorating
    Explanation
    Clue: Since the air is described as ‘pure’ we need a positive word. Also, since doctors recommend it, the air must be good for health.
    Therefore, we choose invigorating which means energizing.
    (soporific = sleep-inducing; debilitating = weakening; insalubrious = unhealthy; aromatic = pleasant-smelling)

    • C.

      Optimism - improving

    • D.

      Complaint - deteriorating

    • E.

      Outlook - escalating

    Correct Answer
    D. Complaint - deteriorating
    Explanation
    Clue: ‘and’ usually joins things of similar meaning or weight. This suggests that since ethics are declining, moral standards are also declining (deteriorating). Almost any word except ‘optimism’ would have fit the first blank.
    (futile = useless, ineffective; escalating = increasing)

      Discoverer - rodent

    • C.

      Writer - organism

    • D.

      Decipherer - denizen

    • E.

      Author - purifier

    Correct Answer
    D. Decipherer - denizen
    Explanation
    Clue: The first blank requires something that conveys what man has done to the genetic code - the only two suitable words are ‘discoverer’ or ‘decipherer’. But since a microbe is not a rodent, we can eliminate that pair.
    (rodent = animal like a rat or mouse; decipherer = someone who decodes; denizen = inhabitant)

    The threat of war, far from ____ , lay heavily in the air, and the villagers, while ____ going about their normal activities, were unable to shake off the feeling of impending catastrophe.

    • A.

      Receding - ostensibly

    • B.

      Diminishing - contentedly

    • C.

      Increasing - apparently

    • D.

      Escalating - joyfully

    • E.

      Subsiding - felicitously

    Correct Answer
    A. Receding - ostensibly
    Explanation
    Clue: ‘Far from’ indicates that an opposite point is being made. So, since there is a feeling of impending catastrophe the threat of war is far from getting less. This indicates that ‘receding’, diminishing’, or ‘subsiding’ might be suitable. We can eliminate these last two since their partner words ‘contentedly’ and ‘felicitously’ are inappropriate for a feeling of danger. So the villagers are only apparently (ostensibly) behaving normally.
    (escalating = increasing ; felicitously = happily, suitably)

    • C.

      Implications - veracity

    • D.

      Errors - truth

    • E.

      Inferences - invalidity

    Correct Answer
    C. Implications - veracity
    Explanation
    Clue: ‘Nothing if not’ means ‘very’. So if the student is very reliable the professor would not doubt the ‘truth’ or ‘veracity’ of the results. Since the student is reliable we can eliminate the ‘error’ choice, and choose ‘implications’.
    (folly = foolishness; impudence = cheekiness; veracity = truth; inferences = something we can deduce)
