The speed of a passenger train is 25% less than that of the express train. 4 hours after the passenger train starts from a station, the express train starts from the same station and completely crossed the passenger in another R hours. What is the value of R ?
» Explain it
B
Let the speed of express train = 4x km per hour

The speed of passenger train = 75% of 4x = 3x km per hour

4 hours after the passenger train start from a station, the express train start from the same station

The distance between the passenger train and express train = 3x × 4 = 12x km

The relative speed of passenger train and express train = 4x – 3x = x km per hour

The time taken by the express train to completely cross the passenger train

 = 12x = 12 hours x

Hence, option B is correct.
2
Pipe P can fill an empty tank in 4 hours but pipe Q can completely empty the same tank in 8 hours. Both the pipes were opened alternately after every two hours starting with pipe P then in how many hours, the tank was completely filled?
» Explain it
C
Let the capacity of the water tank = lcm of 4 and 8 = 16 units

 The efficiency of pipe P = 16 = 4 units per hour 4

 The efficiency of pipe q = 16 = 2 units per hour 8

In the first 2 hours, the units of water filled = 4 × 2 = 8 units

In the next 2 hours, the units of water withdraws = 2 × 2 = 4 units

It means, in one cycle i.e. 4 hours, the total quantity of water filled = 4 units

In the next cycle, the total quantity of water will be filled = 4 × 2 = 8 units

The remaining quantity = 16 – 8 = 8 units

In the next 2 hours, pipe P can fill 8 units of water

Therefore, the total time = 8 + 2 = 10 hours

Hence, option C is correct.

3
At the end of 2 years, the difference between the simple interest and compound interest received on a sum of money is Rs. 500. At the end of 5 years under simple interest, double the sum of money become seven times the sum of money then what was the sum of money? (the rate of interest per annum was same in all the cases)
» Explain it
C
Let the sum of money = Rs. x

Double the sum of money = 2x

The amount received at the end of 5 years = 7x

The total interest = 7x – 2x = 5x

 We know that, SI = P × R × T 100

 5x = 2x × R × 5 100

By solving, R = 50%

The SI at the end of 2 years on Rs. x @ 50% per annum
 = x × 50 × 2 = Rs. x 100

The CI at the end of 2 years on Rs. x @ 50% per annum
 = x × ( 1 + 50 ) 2 – x = 5 = 1.25x 100 4x

According to the question,

1.25x – x = Rs. 500

0.25x = 500

x = 2000

Hence, option C is correct.
4
Ram can complete a piece of work in 20 days. Ram started working alone but at the end of 5 days from starting Mohan joined him and they together complete remaining piece of work in 6 days less than Ram would have taken alone. In how many days, Ram and Mohan together can complete double of the work?
» Explain it
D
According to the question,

 5 + 15 – 6 + 15 – 6 = 1 20 20 mohan

 9 = 1 – 14 = 6 mohan 20 20

The number of days, Mohan will take alone
 = 9 × 20 = 30 days 6

The number of days Ram and Mohan together will take to complete the same piece of work
 = 1 + 1 = 50 = 12 days 20 30 600

Therefore, the number of days they will take to complete double of the work = 12 × 2 = 24 days

Hence, option D is correct.
5
The cost price of an article is Rs. 400. A shopkeeper marked the price 2x percentage above the cost price and gave x% discount on the marked price and earned a profit of Rs. 48. If he had not given discount and had sold the article on the marked price then how much more profit he would have earned?
» Explain it
C
The marked price of the article = (100 + 2x)% of 400 = (100 + 2x) × 4

 The SP = (100 + 2x) × 4 × 100 – x = (100 + 2x) × 4 × ( 1 – x ) 100 100

According to the question,
 (100 + 2x) × 4 × ( 1 – x ) – 400 = 48 100

 (100 + 2x) × 4 × ( 1 – x ) = 448 100

(100 + 2x)(100 – x) = 11200

By solving, x = 20

Therefore, the marked price = (100 + 2x) × 4 = 140 × 4 = 560

The profit = 560 – 400 = 160

The required answer = 160 – 48 = 112

Hence, option C is correct.

Q.1. The speed of a passenger train is 25% less than that of the express train. 4 hours after the passenger train starts from a station, the express train starts from the same station and completely crossed the passenger in another R hours. What is the value of R ?

10
12
15
8
None of these

Explanation:

Let the speed of express train = 4x km per hour

The speed of passenger train = 75% of 4x = 3x km per hour

4 hours after the passenger train start from a station, the express train start from the same station

The distance between the passenger train and express train = 3x × 4 = 12x km

The relative speed of passenger train and express train = 4x – 3x = x km per hour

The time taken by the express train to completely cross the passenger train

= 12x/x = 12 hours

Hence, option B is correct.

Q.2. Pipe P can fill an empty tank in 4 hours but pipe Q can completely empty the same tank in 8 hours. Both the pipes were opened alternately after every two hours starting with pipe P then in how many hours, the tank was completely filled?

6 hours
5 hours
10 hours
12 hours
None of these

Explanation: Let the capacity of the water tank = lcm of 4 and 8 = 16 units

The efficiency of pipe P = 16/4 = 4 units per hour

The efficiency of pipe q = 16/8 = 2 units per hour

In the first 2 hours, the units of water filled = 4 × 2 = 8 units

In the next 2 hours, the units of water withdraws = 2 × 2 = 4 units

It means, in one cycle i.e. 4 hours, the total quantity of water filled = 4 units

In the next cycle, the total quantity of water will be filled = 4 × 2 = 8 units

The remaining quantity = 16 – 8 = 8 units

In the next 2 hours, pipe P can fill 8 units of water

Therefore, the total time = 8 + 2 = 10 hours

Hence, option C is correct..

Q.3. At the end of 2 years, the difference between the simple interest and compound interest received on a sum of money is Rs. 500. At the end of 5 years under simple interest, double the sum of money become seven times the sum of money then what was the sum of money? (the rate of interest per annum was same in all the cases)

Rs. 40000
Rs. 20000
Rs. 2000
Rs. 10000
None of these

Explanation:

Let the sum of money = Rs. x

Double the sum of money = 2x

The amount received at the end of 5 years = 7x

The total interest = 7x – 2x = 5x

We know that, SI = P × R × T/100

5x = 2x × R × 5/100

By solving, R = 50%

The SI at the end of 2 years on Rs. x @ 50% per annum
= x × 50 × 2/100 = Rs. x

The CI at the end of 2 years on Rs. x @ 50% per annum
= x × (1 + 50/100)2 – x = 5/4x = 1.25x

According to the question,

1.25x – x = Rs. 500

0.25x = 500

x = 2000

Hence, option C is correct.

All the above questions through, you must make sure about arithmetic miscellaneous questions which have been seen in the last few years. We hope this above Quantitative Aptitude for SBI Clerk 2020 will clear your all doubts regarding bank clerk exams.
