Question

'A' can do a peace of work in 20 days how much work can he finish in 12days​

Answer 1

Answer:

In 20 days A can do 1 part

ln 1 day A can do 1/20 part

ln 12 days A can do 12/20 part=3/5 part

so, in 12 days A can finish 3/5 part of the work

Answer 2

Remaining work = 1− 3/4 = 1/4

1/20 work is finished by A in 1 day.

1/4 work is finished by A in 20 days

= 20 × 1/4

= 5 × 1/1

= 5

∴ 5 Days
