Question

A can do a piece of work in 60days. he work for 15days and then b done finish the remaining work in 30days . the two together can finish the work in how many days?

Answer 1

Hey Friend ☺

A can do a work in 60 days

So he works 1/60 part of work in one day
He worked for 15 days

So work done = 15 × 1/60

=1/4

Remaining work = 1 - 1/4

= 3/4

B completes the remaining work in 30 days

Let the days taken to complete whole work be x

So .

3/4 × x = 30

3x/4 = 30

x = 30 × 4/3

x = 40

So B can complete the work in 40 days

So B can do 1/40 part of work in one day

A & B can do the work in = 1/40 + 1/60

= 6 + 4/240

=10/240

= 1/24

So A & B can do the whole work in 24 days

Hope it helps you ..!!
