Answer 2

Answer:

7 hours

Step-by-step explanation:

This is a question of indirect proportion.

In indirect proportion product of both scenario are equal.

Let x hours per day is required.

(First scenario = second scenario)

2 * 5 * 21 = 3 * x * 10

10 * 21 / 3 * 10 = x ...(do less calculations)

21 / 3 = x

7 = x

x = 7

Thus they should work 7 hours per day
