A team P of 20 engineers can complete work or task in 32 days. Another team Q of 16 engineers can complete same task in 30 days.Then the ratio of working capacity of 1 member of P to the 1 member of Q is

3 : 2

4 : 3

2 : 5

3 : 5

Explanation:

Let the capacity of an engineer in P = x units, and in Q = y units.

Working capacity of P = x × 32 × 20

Working capacity of Q = y × 16 × 30

As the total work is same, we equate the above equations.

=> x × 32 × 20 = y × 16 × 30

=> xy = 16 × 30 × 32 × 20 = 34
