Question

A finish the work in 10 days. b is 60% efficient than

a. so how days does b take to finish the work?ans : 4days.

Answer 1

A is finish the 100% work in 10 days

B is 60% efficient than

it means B will complete the work 6 day fast to A
then B is complete the work = 10-6 =4 days

Answer 2

It takes 4 days for b to finish the work.

Given,

A finish the work in 10 days. b is 60% efficient than a.

To find,

How days does b take to finish the work?

Solution,

No. of days a can complete the work = 10

Now, b is 60% more efficient than a

So,

No. of days b can complete the work = 10 - (60% of 10)

                                                              = 10 - 6

                                                              = 4 days
