1. 100
2. 1000

4. 2000

Solution: 5 × 5 × x = 100 × 100 × 5 ⇒ x = 2000

Q) A car travels 25km an hour faster than a bus for a journey of 500km. If the bus takes 10 hours more than the car, then the speeds of the bus and the car are

1. 25km/hr and 40km/hr respectively
2. 25km/hr and 60 km/hr respectively
3. 25km/hr and 50km/hr respectively
4. None of these

Solution

Let the speeds of the bus and car be x and y. Here, y = x +25
As per the question, (500/x)-(500/x+25)=10
⇒ 500(x + 25) − 500(x) =10x(x+25) ⇒ x = 25, y = 50.
For such questions, you can also use direct substitution from the given choices

A and B together can complete; a piece of work in 12 days, B and C can do it in 20 days and C and A can do it in 15 days. A, B and C together can complete it in

1. 8 days
2. 10 days
3. 12 days
4. 6 days

Explanation: (A+B)’s 1 day’s work = 1/12
(B+C)’s 1 day’s work = 1/20
(C+A)’s 1 day’s work = 1/15
On adding all there, 2(A+B+C)’s day’s work = (1/12)+(1/20)+(1/15)=1/5
⇒(A+B+C)’s 1 day’s work = 1/10
Hence, the work will be finished in 10 days.

A and B together can complete a work in 3 days. They start together. But, after 2 days, B left the work. If the work is completed after 2 more days. B alone could do the work in

1. 6 days
2. 8 days
3. 10 days
4. 4 days

Explanation: (A+B)’s 2 day’s work = 2/3
Remaining work = 1- (2/3)= 1/3
Time taken by A in 1/3 doing work = 2 days
Time taken by A in completing the work = 6 days
B’s 1 day’s work = (1/3)-(1/6)= 1/6
B alone will complete the work in 6 days
