Capacities of two workers P and Q are in the ratio 3 : 2. What amount of the daily wages of Rs.400 should be given to P?

Ratio of capacities of P and Q = 3:2

Total daily wages = ₹400

The wages are distributed in proportion to the capacities of the workers.

If the total wages are to be distributed in the ratio a : b then:

​$$\text{Wages for P} = \frac{a}{a + b} \times \text{Total Wages}$$​​

The ratio of capacities of P and Q is 3 : 2.

Total parts = 3 + 2 = 5

​$$\text{Wages for P} = \frac{3}{5} \times 400 = \frac{1200}{5} = 240$$​​

Thus, P should be given ₹240 from the daily wages.
