The average speed of a bus is three-fifth the average speed of a car which covers 3250 kms. in 65 hours. What is the average speed of the bus
Correct Answer
A. 30 kmph
Explanation
The average speed of the car can be calculated by dividing the total distance covered (3250 km) by the total time taken (65 hours), which gives us 50 kmph. Since the average speed of the bus is three-fifths of the car's average speed, we can calculate it by multiplying the car's average speed by three-fifths. Therefore, the average speed of the bus is (3/5) * 50 kmph, which equals 30 kmph.

Vijay donates blood thrice in two years each time 350 ml. How many litres of blood will he donates in 6 years?
Correct Answer
B. 3.15
Explanation
In two years, Vijay donates blood thrice, which means he donates a total of 3 x 350 ml = 1050 ml of blood. Since there are 1000 ml in 1 liter, Vijay donates 1050/1000 = 1.05 liters of blood in two years. Therefore, in 6 years, he will donate 3 x 1.05 = 3.15 liters of blood.

If a number is added to two-fifth of itself, the value so obtained is 455. What is the number?
Correct Answer
C. 325
Explanation
The question states that if a number is added to two-fifth of itself, the result is 455. To find the number, we can set up an equation. Let's assume the number is x. Two-fifth of x is (2/5)x. Adding x to (2/5)x gives us the equation x + (2/5)x = 455. Simplifying this equation, we get (7/5)x = 455. To solve for x, we can multiply both sides of the equation by 5/7. This gives us x = (455 * 5)/7 = 325. Therefore, the number is 325.

The body weight of seven students of a class is recorded as 54 kg., 78 kg., 43 kg., 82 kg., 67 kg., 42 kg., and 75 kg., What is the average body weight of all the seven students?
Correct Answer
B. 63 kg.
Explanation
The average body weight of all the seven students can be calculated by adding up the individual weights of the students and then dividing the sum by the total number of students. In this case, the sum of the weights is 54 + 78 + 43 + 82 + 67 + 42 + 75 = 441 kg. Since there are seven students, the average body weight would be 441 kg divided by 7, which equals 63 kg.

What will come in place of the question marks (?) in the following number series? 9, 21, 45, 81, 129, (?)
Correct Answer
D. 189
Explanation
The given number series follows the pattern of adding consecutive odd numbers. Starting with 9, the first odd number 2 is added to it, resulting in 11. Then, the next odd number 4 is added to 11, resulting in 15. This pattern continues, with each consecutive odd number being added to the previous number in the series. Therefore, the next odd number 8 will be added to 129, resulting in 137. Finally, adding 8 to 137 gives us the missing number in the series, which is 145.
12.
What will come in place of the question marks (?) in the following number series? 652, 428, 316, 260, 232, (?)
Correct Answer
A. 218
Explanation
The given number series follows a pattern where each number is obtained by subtracting a certain value from the previous number. In this series, the pattern is as follows: 652 - 224 = 428, 428 - 112 = 316, 316 - 56 = 260, 260 - 28 = 232. Therefore, to find the next number, we subtract 14 from 232, resulting in 218. Hence, the correct answer is 218.

Ganeshi's monthly income is twice that of jassi's monthly income . Two thrid of jassi's monthly income is equal to Sukhwinder's monthly income . If Sukhwinder annual income is Rs. 2.34 lacs . What is Ganeshi's monthly income ?( In some cases annual income and in some cases monthly income is given.)
Correct Answer
C. Rs. 58,500
Explanation
The question states that Sukhwinder's annual income is Rs. 2.34 lacs. To find Ganeshi's monthly income, we need to first find Jassi's monthly income. It is given that two-thirds of Jassi's monthly income is equal to Sukhwinder's monthly income. So, Jassi's monthly income can be calculated by dividing Sukhwinder's annual income by 12 and then multiplying it by 2/3. Once we have Jassi's monthly income, we can find Ganeshi's monthly income by multiplying it by 2. Therefore, the correct answer is Rs. 58,500.

The angles of a triangle are in ratio of 3 : 5 : 4 respectively. What is the difference between twice the smallest angle and the second largest angle of the triangle?
Correct Answer
D. 30Â°
Explanation
The angles of a triangle are in the ratio of 3:5:4. Let's assume the smallest angle is 3x, the second largest angle is 5x, and the largest angle is 4x. The sum of the angles of a triangle is 180Â°, so we can set up the equation 3x + 5x + 4x = 180Â°. Solving this equation, we find that x = 12Â°. Therefore, the smallest angle is 3(12Â°) = 36Â° and the second largest angle is 5(12Â°) = 60Â°. Twice the smallest angle is 2(36Â°) = 72Â°. The difference between 72Â° and 60Â° is 72Â° - 60Â° = 12Â°. However, the question asks for the difference between twice the smallest angle and the second largest angle, so the correct answer is 72Â° - 60Â° = 30Â°.

One of the angle of a parallelogram is . What is the sum of half the smallest angle and twice the largest angle of the parallelogram?
Correct Answer
C. 297Â°
Explanation
The sum of half the smallest angle and twice the largest angle of a parallelogram can be found by using the properties of a parallelogram. In a parallelogram, opposite angles are equal. Since one angle of the parallelogram is given as 256Â°, the opposite angle will also be 256Â°. Therefore, the smallest angle of the parallelogram is 256Â°. The largest angle of the parallelogram will be the opposite angle, which is also 256Â°. Hence, half the smallest angle is 128Â° and twice the largest angle is 512Â°. The sum of these two angles is 128Â° + 512Â° = 640Â°. However, none of the given answer choices match this sum. Therefore, the correct answer cannot be determined.

In how many different ways can the letters of word 'REMAKE' be arranged?
Correct Answer
C. 360
Explanation
The word "REMAKE" has 6 letters. To find the number of different ways these letters can be arranged, we use the formula for permutations of n objects taken all at a time, which is n!. In this case, 6! = 6 x 5 x 4 x 3 x 2 x 1 = 720. However, since the letter "E" appears twice, we must divide by the factorial of the number of times it repeats, which is 2!. Therefore, the total number of different ways the letters of the word "REMAKE" can be arranged is 720 / 2! = 360.

The perimeter of a square is equal to the perimeter of a rectangle of lenght 30 cms. The area of the rectangle is 360 sq. cm. What is the side of the square?
Correct Answer
B. 21 cm.
Explanation
The perimeter of a square is equal to 4 times its side length. The perimeter of the rectangle is equal to 2 times its length plus 2 times its width. Given that the perimeter of the square is equal to the perimeter of the rectangle, we can set up the equation 4s = 2(30) + 2w, where s is the side length of the square and w is the width of the rectangle. Since the area of the rectangle is 360 sq. cm, we can also set up the equation lw = 360. Solving these two equations simultaneously, we find that the side length of the square is 21 cm.
