Question 1: A can complete a work alone in 25 days while B can complete the same work alone in 10 days. A started doing the work but after 5 days he is replaced by B who completed the remaining work. In how many days the work got completed?

a. 13 days

b. 12 days

c. 15 days

d. 10 days

e. 18 days

Answer: a

Solution:

Let the total work = 50 units (L.C.M of 25 and 10)

Efficiency of A = 50/25 = 2 units/day

Efficiency of B = 50/10 = 5 units/day

Amount of work done by A in 5 days = 2 × 5 = 10 units

Remaining work = 50 – 10 = 40 units

Time taken by B to complete the remaining work = 40/5 = 8 days

Total number of days = 8 + 5 = 13 days

Hence, option a.

Question 2: The ratio of length of train A to train B is 5:4. Train A and B can cross a man in 30 seconds and 20 seconds respectively. Find the speed of the train B if the speed of train A is 72 km/h.

a. 82.4 km/h

b. 86.4 km/h

c. 80.4 km/h

d. 92.4 km/h

e. 75.4 km/h

Answer: b

Solution:

Length of train A = 72 × 5/18 × 30 = 600

Length of train A = 600 m

Length of train B = 4/5 × 600 = 480 m

Speed of train B = 480/20 × 18/5 = 86.4 km/h

Hence, option b.

Question 3: A boat takes twice as much time to row a certain distance upstream as to row the same distance downstream. If the speed of the stream is 6 km/h, then find the time taken by it to row 108 km downstream and 42 km upstream.

a. 6 hours

b. 8 hours

c. 7.5 hours

d. 5.5 hours

e. 10 hours

Answer: b

Solution:

Let the speed of the boats in still water = x km/h

According to question: Downstream speed of the boat = 2 × upstream speed of the boat

x + 6 = 2 × (x – 6)

x + 6 = 2x – 12

x = 18

Time taken by the boat to cover 108 km downstream and 42 km upstream = 108/(18 + 6) + 42/(18 – 6)

= 4.5 + 3.5 = 8 hours

Hence, option b.

Question 4: A shopkeeper sold an article at two successive discounts of 20% and 25% respectively. If the article is sold at 20% profit, then by how much percent the article was marked up above its cost price?

a. 80%

b. 100%

c. 120%

d. 50%

e. 200%

Answer: b

Solution:

Let the marked price of the article be Rs. x

Therefore, selling price of the article = 0.75 × 0.80x = Rs. 0.6x

Cost price of the article = (0.6x/1.2) = Rs. 0.5x

Required percentage = {(x – 0.5x)/0.5x} × 100 = 100%

Hence, option b.

Question 5: Find the sum of all the numbers between 128 and 624, which are divisible by ‘9’ as well as’8’.

a. 2380

b. 2240

c. 2520

d. 2680

e. 2420

Answer: c

Solution:

Numbers which are divisible by ‘9’ as well as ‘8’, must be divisible by 72.

So, numbers between 128 and 624 which are divisible by 72 are:

144, 216, ……….., 576

So, number of terms between 128 and 624 which are divisible by 72 = n = {576 – 144}/72 + 1 = 7

Desired sum = (7/2) × {144 + 576} = 7 × 360 = 2520

Hence, option c.

Question 8: The income of A is Rs. 5000 more than that of B, while the expenditure of A is Rs. 5000 less than that of B. If the savings of A and B is Rs. 20,000 and Rs. 10,000 respectively, then find the income of A.

a. Rs. 35000

b. Rs. 38000

c. Rs. 45000

d. Rs. 50000

e. cannot be determined

Answer: e

Solution:

Let the income of A be Rs. x

Therefore, income of B = Rs. (x – 5000)

Let the expenditure of A be Rs. y

Therefore, expenditure of B = Rs. (y + 5000)

According to the question,

x – y = 20000……. (1)

And, x – 5000 – y – 5000 = 10000

Or, x – y = 20000…. (2)

Therefore, income of A cannot be determined.

Hence, option e.
