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
