If 18 mechanics can repair 90 cars in 10 days, how many mechanics will be required to repair 150 cars in 12 days?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 25.
Let the number of mechanics required = x
So, (18 × 10)/90 = (x × 12)/150
⇒ 2 = 2x/25
⇒ x = 25
Hence, 25 machines will be required.
