I want the solution of Q.2 for the questions you can see the above attachment?​

Answer 1

Answer:

Hi,

Given that A can finish a piece of work in 6 days,

So, in one day A will do 1/6 th of work,

Given that B can finish a piece of work in 4 days,

So, in one day B will do 1/4 th of work,

Given that initially A has worked for 2 days,

So A will complete 2*1/6 = 1/3 rd of work

Remaining Work = 2/3 rd of work.

If A and B works together,

In 1 day, bot A and B could do = (1/6 + 1/4) of work

= 5/12 th of work

So, 2/3 rd of work requires 2/3*1/(5/12)

= 8/5 days,

Total time , to finish the work

= Time A working alone an Time taken when both A and B are

working together

= 2 + 8/5

= 18/5 days

Hope, it helps
