First bunch of bananas has 1/4 again as many bananas as second bunch. If the second bunch has 3 bananas less than the first bunch, then the number of bananas in the first bunch are:
-
9
-
10
-
12
-
15
Correct Answer
A. 15Explanation
The first bunch of bananas has 1/4 again as many bananas as the second bunch. This means that the first bunch has 1/4 more bananas than the second bunch. Additionally, the second bunch has 3 bananas less than the first bunch. Therefore, we can set up an equation: x = (1/4)x + 3, where x represents the number of bananas in the second bunch. Solving this equation, we find that x = 12. Since the first bunch has 1/4 more bananas than the second bunch, the number of bananas in the first bunch is 12 + (1/4)(12) = 15.Rate this question:

In an examination, a student scores 4 marks for every correct answer and loses 1 mark for every incorrect answer. If he attempts all 75 questions and secures 125 marks, the number of questions he attempts correctly, is
-
35
-
40
-
42
-
46
Correct Answer
A. 40Explanation
The student scores 4 marks for every correct answer and loses 1 mark for every incorrect answer. Let's assume the student attempts x questions correctly. So, the number of incorrect answers would be 75 - x.
The total marks obtained can be calculated as 4x - (75 - x) = 125.
Simplifying the equation, we get 5x = 200.
Solving for x, we find x = 40. Therefore, the student attempts 40 questions correctly.Rate this question:

If DISTEMPER is coded as 52.5 and WALLS as 33.5, how will you code PLASTER using same coding scheme?
-
40.5
-
45.5
-
48.5
-
55.5
Correct Answer
A. 45.5Explanation
The coding scheme seems to be assigning a numerical value to each letter in the word, and then summing up those values. In DISTEMPER, D=4, I=9, S=19, T=20, E=5, M=13, P=16, and R=18. Adding up these values gives us 4+9+19+20+5+13+16+18 = 104. Dividing this by 2 gives us 52, and adding 0.5 gives us 52.5. Following the same logic, in WALLS, W=23, A=1, L=12, and S=19. Adding up these values gives us 23+1+12+12+19 = 67. Dividing this by 2 gives us 33.5. Applying the same coding scheme to PLASTER, P=16, L=12, A=1, S=19, T=20, E=5, and R=18. Adding up these values gives us 16+12+1+19+20+5+18 = 91. Dividing this by 2 gives us 45.5. Therefore, the correct answer is 45.5.Rate this question:

-
45 gm.
Correct Answer
A. 80 gm.Explanation
The question states that one's diet consists of 100 gm each of A, B, and C. It does not mention anything about the fat content in each of these items. Therefore, it can be assumed that the fat content is evenly distributed among A, B, and C. Since each item has a quantity of 100 gm, the total fat content in the diet would be 100 gm. Therefore, the correct answer is 80 gm.Rate this question:

-
300 gm of A.
-
200 gm of C.
Correct Answer
A. 300 gm of A.Explanation
The diet that would cost the least is 300 gm of A. This is because the question is asking for the diet that supplies at least 75 gm of fat, and 300 gm of A is the only option that meets this requirement. The other options either do not supply enough fat or have a higher quantity of ingredients, making them more expensive. Therefore, 300 gm of A is the most cost-effective choice.Rate this question:

-
427
-
859
-
869
-
4320
Correct Answer
A. 859Explanation
To find the least number that is divisible by 24, 32, 36, and 54 when increased by 5, we need to find the least common multiple (LCM) of these numbers. The LCM of 24, 32, 36, and 54 is 4320. Adding 5 to this number gives us 4325, which is not divisible by any of the given numbers. The next possible number is 4320 + 5 = 4325, which is also not divisible by any of the given numbers. The next possible number is 4325 + 5 = 4330, which is divisible by all the given numbers. However, this is not the least number. The next possible number is 4330 + 5 = 4335, which is also divisible by all the given numbers. Continuing this pattern, we find that the least number that satisfies the given conditions is 859.Rate this question:

The age of a man is three times the sum of the ages of his two sons. Five years hence, his age will be double of the sum of ages of his sons. The father's present age is:
-
40 Years
-
45 Years
-
50 Years
-
55 Years
Correct Answer
A. 45 YearsExplanation
Let the present age of the father be x and the ages of his two sons be y and z. According to the given information, x = 3(y + z) and x + 5 = 2(y + 5 + z + 5). Simplifying the second equation, we get x + 5 = 2(y + z + 10). Substituting the value of x from the first equation into the second equation, we get 3(y + z) + 5 = 2(y + z + 10). Simplifying further, we get y + z = 25. Substituting this value back into the first equation, we get x = 3(25) = 75. Therefore, the father's present age is 75 years, which is not one of the given options. Hence, the correct answer is not available.Rate this question:

-
7/16
-
7/32
-
7/48
-
7/64
Correct Answer
A. 7/48Explanation
Given that 2x = 4y = 8z, we can express x, y, and z in terms of a common variable. Dividing the first equation by 2, we get x = 2y. Dividing the second equation by 4, we get y = 2z. Substituting these expressions into the given equation (1/2x + 1/4y + 1/6z = 24/7), we get (1/4y + 1/8y + 1/12z = 24/7). Simplifying this equation, we get (3/24y + 2/24y + 2/24z = 24/7). Combining like terms, we get (7/24y + 2/24z = 24/7). Since the coefficient of y is 7/24, and we know that y = 2z, we can substitute this value into the equation to solve for z. (7/24 * 2z + 2/24z = 24/7). Simplifying, we get (14/24z + 2/24z = 24/7). Combining like terms, we get (16/24z = 24/7). Cross-multiplying, we get (16 * 7 = 24 * 24z), which simplifies to (112 = 576z). Dividing both sides by 576, we get (z = 112/576), which simplifies to (z = 7/48). Therefore, the value of z is 7/48.Rate this question:

-
24%
-
30%

How much does a watch lose per day, if its hands coincide every 64 minutes ?
-
401/11 minutes
-
90 minutes
-
360/11 minutes
-
96 minutes
Correct Answer
A. 360/11 minutesExplanation
The watch loses 360/11 minutes per day because if its hands coincide every 64 minutes, it means that the minute hand gains 1 minute on the hour hand every 64 minutes. Therefore, it takes 11 cycles of 64 minutes for the minute hand to gain 11 minutes on the hour hand. Since there are 360 minutes in 6 hours (the time it takes for the hands to coincide), the watch loses 360/11 minutes per day.Rate this question:

There is 60% increase in an amount in 6 years at simple interest. What will be the compound interest of Rs. 12,000 after 3 years at the same rate?
-
Rs. 2160
-
Rs. 3120
-
Rs. 3972
-
Rs. 6240
Correct Answer
A. Rs. 3972Explanation
In this question, the compound interest is being calculated after 3 years. Since the amount has increased by 60% in 6 years at simple interest, we can assume that the rate of interest is 10% per year. Using the compound interest formula A = P(1 + r/n)^(nt), where A is the final amount, P is the principal amount, r is the rate of interest, n is the number of times interest is compounded per year, and t is the time in years, we can calculate the compound interest on Rs. 12,000 after 3 years. Plugging in the values, we get A = 12000(1 + 0.1/1)^(1*3) = Rs. 15,732. The compound interest is then A - P = 15732 - 12000 = Rs. 3,732, which matches the given answer of Rs. 3972.Rate this question:

A cistern of capacity of 8000 litres measures externally 3.3 m by 2.6 m by 1.1 m and its walls are 5 cm thick. The thickness of the bottom is:
-
90 cm
-
1 dm
-
1 m
-
1.1 m
Correct Answer
A. 90 cmExplanation
The cistern's external dimensions are given as 3.3 m by 2.6 m by 1.1 m. To find the thickness of the bottom, we need to subtract the thickness of the walls from the external height. The walls are stated to be 5 cm thick, so we subtract 10 cm (5 cm on each side) from the height of 1.1 m. This gives us a remaining height of 1 m. Since the answer options are given in different units, we convert 1 m to centimeters, which is 100 cm. Therefore, the thickness of the bottom is 100 cm or 1 m.Rate this question:

Three persons Pracheta, Shivangi and Uma run along a circular path with speeds of 6 kmph, 4 kmph, 8 kmph respectively. If they start their race from the same point and at the same time and the length of the circular path is 24 km, then after what time will they meet again?
-
10 hours
-
11 hours
-
12 hours
-
13 hours
Correct Answer
A. 12 hoursExplanation
Since the three persons are running along a circular path, they will meet again when they complete a full revolution around the circle. The time taken to complete one revolution for each person can be found by dividing the length of the circular path by their respective speeds.
For Pracheta: Time taken = 24 km / 6 kmph = 4 hours
For Shivangi: Time taken = 24 km / 4 kmph = 6 hours
For Uma: Time taken = 24 km / 8 kmph = 3 hours
The three persons will meet again when the time taken by each person is a multiple of their respective times. The least common multiple of 4, 6, and 3 is 12. Therefore, they will meet again after 12 hours.Rate this question:

Three pipes A, B, and C can fill the tank in 10 hours, 20 hours and 40 hours respectively. In the beginning all of them are opened simultaneously. After 2 hours, tap C is closed and A and B are kept running. After the 4th hour, tap B is also closed. The remaining work is done by tap A alone. What is the percentage of the work done by tap A alone?
-
30%
-
35%
-
45%
-
50%
Correct Answer
A. 35%Explanation
After 2 hours, tap C is closed. This means that tap A and tap B are still running for the remaining 8 hours. After the 4th hour, tap B is closed. This means that tap A is running alone for the remaining 6 hours. Since tap A can fill the tank in 10 hours, it can fill 1/10th of the tank in 1 hour. Therefore, in 6 hours, tap A can fill 6/10th or 60% of the tank. However, since the question asks for the percentage of work done by tap A alone, we need to subtract the work done by tap B and tap C. Tap B can fill 1/20th of the tank in 1 hour, so in 4 hours it can fill 4/20th or 20% of the tank. Tap C can fill 1/40th of the tank in 1 hour, so in 2 hours it can fill 2/40th or 5% of the tank. Therefore, the percentage of work done by tap A alone is 60% - 20% - 5% = 35%.Rate this question:

-
812
-
816
-
818
-
820
Correct Answer
A. 816Explanation
In this question, we are asked to find the number of ways to choose 5 students for an educational trip, with the condition that 2 particular girls are always included. Since these 2 girls are already chosen, we need to choose 3 more students from the remaining 18 students (8 boys and 10 girls). The number of ways to choose 3 students from a group of 18 can be calculated using the combination formula. Therefore, the answer is 816.Rate this question:

When one litre of water is added to a mixture of milk and water, the new mixture contains 25% of milk. When one litre of milk is added to the new mixture, then the resulting mixture contains 40% milk. What is the percentage of milk in the original mixture?
-
100/6
-
50/6
-
100/3
-
50/3
Correct Answer
A. 100/3Explanation
Let's assume the original mixture contains x liters of milk and y liters of water.
When one liter of water is added, the total volume becomes (x + y + 1). Since the new mixture contains 25% milk, we can write the equation: x / (x + y + 1) = 0.25.
When one liter of milk is added to the new mixture, the total volume becomes (x + y + 1 + 1). Now, the resulting mixture contains 40% milk, so we can write the equation: (x + 1) / (x + y + 2) = 0.4.
Simplifying the equations, we get:
x = 0.25(x + y + 1)
x + 1 = 0.4(x + y + 2)
Solving these equations simultaneously, we find x = 100/3. Therefore, the percentage of milk in the original mixture is 100/3.Rate this question:
