D. 520
Answer: Option A
Solution (By Examveda Team)
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 matsThis Question Belongs to Arithmetic Ability >> Time And Work
It's possible just read question carefully.
In 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.
answer 560
The answer is true man ...see
8 men + 4 boys = 20 boys
20 boys work = 260/20 *20
= 260 mats
may be answer is 130..........260 is not possible
not possible in both equations only men different but work and hour was same?
