Question

A can do a piece of work in 24days while B can do it in 30 days in how many days can they do it together?​

Answer 1

Step-by-step explanation:

A can do a piece of work=24days

so, how much work A do in 1 day=1/24 work

similarly, B can do a work =30 days

so, in 1day=1/30

hence, according to question

A+B(together how much work)=1/24+1/30=9/120

so, how much work do together, just reversed the answer9/120=120/9

=13.333 is the answer of this question.

just says they do a work in 13 days 3hours.
