44. A can do a piece of work in 12 days while Balone can15 days. With the help of they can finish it in 5 daythey are paid 960 for the whole work how much moneygets?

Answer»

IF A, B and C work together, they will finish job in

= ABC/( AB+BC+CA) =5 Substitute A=12, B=15.

Therefore, C= 4

A, B & C compete works in 12, 15 & 4 days respectively, if they work alone.

C(4 days) is three times more efficient then A ( 12 days). B ( 15 days) is 3/5 times efficient than A ( 12 days).

If X is the efficiency of A. Then Eff. of A + Eff. of B + Eff. of C = 960X+(3/5)X + 3X = 960X= 208.7

A gets Rs 208.7B gets Rs 125.22 C gets Rs 626.7.
