Question

mayank can do a piece of work in 24 days while suresh can do it in 30 days. In how many days can they complete it, if they work together ?​

Answer 1

Step-by-step explanation:

mayank can do a piece of work in 24 day

Suresh can do it in 30 days

LCM OF 24 AND 30=120

work done by mayank in one day =120÷24=5

" " " suresh in one day =120÷30=4

total work done in one day=5+4=9 and total work is 120

number of days=120÷9=13.3

Answer 2

Answer:

40/3 days

Step-by-step explanation:

Mayank can do a piece of work in 24days,so in 1 day he can do =1/24of the work.

Similarly ,Suresh can do 1/30 of the piece of the work in 1 day.

So , together they can do = 1 / 24 + 1 /30 of the piece of the work in 1 day = 9 /120 of the work = 3/40 of the work in 1 day.

So together they can do the work in 40 / 3 days
