Question

Anu, Babu and Chitra, each working alone can complete a job in 6, 8 and 12 days respectively. If all three of them work together to complete a job and earn Rupees 2340, what will be Chitra's share of the earnings?

Answer is 520.

Answer 1

Chitra's one day's work =

1/6 + 1/8 + 1/12 = 27/72 = 3/8

Anu's wage: babu's wage: chitra's wage = 1/6+1/8+72/27

Chitra's share (for 12 days) = Rs.12 x27/72 x 2400

= Rs. 520.
