Question

Amit can do a piece of work in 5 days and submit in 4 days. How long will they take to do the same work, if they work together? Using propitiation formula

Answer 1

Amit can do work in = 5 days
1 day work of Amit = 1/5 part
Sumit can do work in = 4 days
1 day work of Sumit = 1/4 part
1 day work if they work together = 1/5 + 1/4
= 4+5/20
= 9/20
They can finish the work in = 20/9 days

Answer 2

Answer:

Amit work :4 days

1 works = 1/4 days

Sumit works:5 days

1 work =1/5 days

work together:1/4+1/5=5+4/20=20/9 days ,
