Question

If it takes 2 garage mechanics 3 hours to repair 6 cars, how many mechanics would it take to repair 22 cars in 5 hours?

Answer 1

2 garage mechanics take 3 hours to repair 6 cars.
to repair 1 car, 1 garage mechanics take = (2×3)/6 = 1 hour

So In 1 hour, 1 car can be repaired by 1 mechanic
22 cars can be repaired in 1 hour by = 22/1 = 22 mechanics
22 cars can be repaired in 5 hours by = 22/5 = 4.4 = 5 mechanics
(4.4 mechanics are not possible. There should be 5 mechanics)

So it would take 5 mechanics to repair 22 cars in 5 hours

Answer 2

2 garrage mechanics tke 3 hrs to repair 6 cars therefore 1 takes......... 1 hour.

therefore 22 cars can be repaired by 22/5 = 4.4 approx 5 mechanics
