Q1. A train running at 54 kmph takes 20 sec to pass a platform. Next it takes 12 sec to pass a man walking at 6 kmph in the same direction in which the train is going. Find the length of platform?

A. 160 m
B. 140 m
C. 112 m
D. none of these

ANS: B

Explanation:

Relative speed with respect to man = 54 - 6 = 48 kmph The length of the train is 48 * 5/18 * 12 =160 m Time taken to pass platform = 20 sec Speed of the
train = 54 * 5/18 =15 m/s 160+x = 20 *15 x = 140 m Length of the platform is 140 m

Q2. A man invested 3/3 of his capital at 7% , 1/4 at 8% and the remainder at 10% If his annual income is Rs.561. The capital is:

A. 5200
B. 6600
C. 4800
D. none of these

ANS: B

Explanation:

Let the capital be Rs. x. Then, (x/3 + 7/100 + 1) + (x/4 + 8/100 + 1) + (5x/12 + 10/100 +1) = 561 7x/300 + x/50 + x/24 = 561 51x = 561 * 600 x = 6600.

Q3. At a special sale, 5 tickets can be purchased for the price of 3 tickets. If 5 tickets are purchased at the sale, the amount saved will be What percent of the original price of the 5 tickets?

A. 20%
B. 33.3%
C. 40%
D. 60%

ANS: C

Explanation:

Let the cost of single ticket be \$x. The cost of 3 tickets is \$3x. The cost of 5 tickets is \$5x. The amount saved, when 5 tickets are purchased at sale = 5x - 3x = \$2x The percent of the amount saved to the original price of the 5 tickets = (2x/5x)*100 = 40%

Q4. A cylindrical container has a radius of eight inches with a height of three inches. Compute how many inches should be added to either the radius or height to give the same increase in volume.

A. 16/5 inches
B. 16/3 inches
C. 16/7 inches
D. none of these

ANS: B

Explanation:

Let x be the amount of increase. The volume will increase by the same amount if the radius increased or the height is increased.
So, the effect on increasing height is equal to the effect on increasing the radius. i.e., (22/7)*8*8*(3+x) = (22/7)*(8+x)*(8+x)*3 Solving the
quadratic equation we get the x = 0 or 16/3. The possible increase would be by 16/3 inches.

A. Brother
B. Sister
C. Nephew
D. Cannot be determined

ANS: D

Explanation:

If D is Male, the answer is Nephew. If D is Female, the answer is Niece. As the sex of D is not known, hence, the relation between D and A cannot be determined. Note: Niece - A daughter of ones brother or sister, or of ones brother-in-law or sister-in-law. Nephew - A son of ones brother or sister, or of ones brother-in-law or sister-in-law.

Q9. What is the length of a running train?
I. The train crosses a man in 9 seconds.
II. The train crosses a 240 metre long platform in 24 seconds.

A. I alone is sufficient while II alone not sufficient to answer.
B. II alone is sufficient while I not alone sufficient to answer.
C. Either I or II alone sufficient to answer.
D. Both I and II are necessary to answer.

ANS: D

Explanation:

Time taken by train to cross a man = Length of train/Speed of train = Speed = l/9 ...
(i) Time taken by train to cross a platform = (Length of train + Length of platform)/Speed of train = Speed = (l+240)/24...
(ii) From (i) and (ii), we get l/9 = (l+240)/24 Thus, l can be obtained. So both I and II are necessary to get the answer.

Amount = Rs.110, True Discount = Rs.10, Present worth = Amount-True Discount =Rs.110-10 =Rs.100 SI on Rs.100 for a certain time =Rs.10
SI on Rs.100 for double the time =Rs.20 True Discount on (100+20)=120-100 =Rs.20 True Discount on Rs.110 =(110*20)/120 =Rs.18.33

Q17. The ratio of the age of a man & his wife is 4:3.After 4 years this ratio will be 9:7. If the time of marriage the ratio was 5:3, then how many years ago were they married?

A. 32
B. 24
C. 12
D. none of these

ANS: C

Explanation:

The age of a man is 4x. The age of his wife is 3x. After 4 years their ratios will be 9:7 i,e, 4x + 4/3x+4 = 9/7 28x - 27x = 36 - 28 x = 8. Age of a man
is 4x = 4*8 = 32 years. Age of his wife is 3x = 3*8 = 24 yeras. Let us assume y years ago they were married, the ratio was 5:3 i.e. 32 - y/24 - y = 5/3 y = 12 years.
i.e. 12 years ago they were married.

C. 63
D. none of these

ANS: B

Explanation:

Let the capacity of P be x litre. Then capacity of Q = x/3 litre. Capacity of the drum = 60x litre. Required number of turns = 60x/ (x+(x/3)) = 60x * 3/4x = 45

Q19. A man spends 2/5 of his salary on house rent, 3/10 of his salary on food, and 1/8 of his salary on conveyance. if he has Rs 1400 left with him, find his expenditure on conveyance?

A. 2400
B. 1000
C. 1800
D. none of these

ANS: B

Explanation:

Part of the salary left = 1 - [2/5 + 3/10 + 1/9] = 1 - 33/40 = 7/40 Let the monthly salary be Rs x. Then, 7/40 of x = 1400 x = [1400 * 40] / 7 x = 8000
Expenditure on food = 3/10 * 8000 = Rs 2400 Expenditure on conveyance = 1/8 *8000 = Rs 1000
