Step-by-step explanation:
( 2 men + 3 boys) x 10 days
= ( 3 men + 2 boys ) x 8 days
20 Men + 30 boys = 24 men + 16 boys
2 men is = 7 boys
2 men + 1 boy =7 boys + 1 boy =8 boys
1 men + 1 boy = 7 boys + 1 boy = 8 boys
2 men + 3 boys = 7 boys + 3 boys
10 boys can do a piece of work in 10 days
1 boy can do a piece of work in
10x10 days
8 boys can do a piece of work in
