The ratio of efficiencies of P, Q and R is 2 : 3 : 4. While P and R work on alternate days and Q work for all days. Now the work completed in total 10 days and the total amount they get is Rs. 1200. Find the amount of each person(respectively).

Correct Answer: 200, 600, 400

Explanation:

Ratio of efficiencies of P, Q and R = 2 : 3 : 4


From the given data,


Number of working days of P, Q, R = 5 : 10 : 5


Hence, ratio of amount of p, Q, R = 2x5 : 3x10 : 4x5 = 10 : 30 : 20


Amounts of P, Q, R = 200, 600 and 400.
