Question

Hey guys, please help me with my question...

Answer 1

Answer:

a man can do a peice of work in = 8days

he can do 1/8 in = 1 day

he can do 1/4(2/8) work in = 2days

the work left is 3/4

2 men can do 1/4 work in one day

$\frac{3}{4} \div \frac{1 }{4} = \frac{3}{4 } \times \frac{4}{1 } = 3days$

they will complete the work in

1 + 3 days = 4 days
