Answer 1

Answer:

12 days

Step-by-step explanation:

Given,

A and B working separately can do a piece of work in 10 days and 15 days respectively

A=1/10; B=1/15

total work LCM of 15,10 is 30p

A's 1 part of work in 1/10 days

     30p of work in 30/10=3p

B's 1 part of work in 1/15 days

     30p of work in 30/15=2p

A can do 3p of work in 1 day

B can do 2p of work in next day

Total 5p=2 days

        30p=12 days
