Question

A does 20% less work than B. If A can finish a piece of work in 15/2 hours, then B can finish it in

​

Answer 1

Answer:

Solution:-

Ratio of percentage of work done by A and B = 80 : 100

Suppose B takes 'x' hours time to complete the work.

So,

⇒ 80 : 100 :: x : 15/2

⇒ 100x = 15/2*80

⇒ x = 600/100

⇒ x = 6 hours  (Time taken by B)
