If 40 men can make 30 boxes in 20 days, How many more men are needed to make 60 boxes in 25 days?
-
- 20
- 24
- 27
- 28
Correct Option: B
Given in the question,
M1 = 40 Men , D1 = 20 days , W1 = 30 Boxes
M2 = 40 + M , D2 = 25 days , W2 = 60 Boxes
We know that ,
⇒ | M1D1 | = | M2D2 |
W1 | W2 |
⇒ | 40 x 20 | = | ( 40 + M ) x 25 |
30 | 60 |
⇒ 40 x 20 x 2 = ( 40 + M ) x 25
⇒ ( 40 + M ) = | 40 x 20 x 2 |
25 |
⇒ ( 40 + M ) = 8 x 8 = 64 men ⇒ M = 64 - 40 = 24 men
