Question

fill in the blanks. If Murshid can do a piece of work in 20 days, he can to 1/5 of the work in _______ 5 days.​

Answer 1

Answer:

alone could finish all of the work in 20 days , which means he can do 1/20 work each day . Since he works for 5 days he completes 5*(1/20) = 1/4 work .

Now the remaining work i.e 3/4 work is done by B . Takes takes 10 days to complete 3/4 work . This means in each day he completes (3/4)/10 = 3/40 work

So A can finish 1/20 work each day and B can finish 3/40 work , each day . So , together he can finish 1/20 + 3/40 = 5/40 = 1/8 work a day .

This means together they take 8 days to complete the work .
