If 10 men or 20 boys can make 260 mats in 20 days, then how many mats will be made by 8 men and 4 boys in 20 days?
Answer & Solution
Correct Answer:
Option
A
10 men = 20 boys
→1 men = 2 boys
8 men = 2 × 8 boys = 16 boys
Then, (16 boys + 4 boys) = 20 boys can make 260 mats in 20 days
Now,
It can be calculated by work equivalence method:
20 × 260 × 20 = x × 20 × 20
x = 260 mats

LoginIn 1st sentence OR is there, means only 20 boys making 260 mates either you can take as only 10 men is making 260 mates.
But in 2 sentence both boys + men togather making mates. So the answer will be 260 only.
8 men + 4 boys = 20 boys
20 boys work = 260/20 *20
= 260 mats
