5.
A alone can do a piece of work in 6 days and B alone in 8 days. A and B undertook to do it for Rs. 3200. With the help of C, they completed the work in 3 days. How much is to be paid to C?
Rs. 375
Rs. 400
Rs. 600
Rs. 800
Answer: Option
Explanation:

C's 1 day's work = 1 - 1 + 1 = 1 - 7 = 1 .
3 6 8 3 24 24

A's wages : B's wages : C's wages = 1 : 1 : 1 = 4 : 3 : 1.
6 8 24

C's share (for 3 days) = Rs. 3 x 1 x 3200 = Rs. 400.
24

1/24 is the work done by C in one day. For three days "3" is used.

I agree with siddharth, either the 3 should be removed or they should mention that A,B,C charge Rs 3200 "PER DAY"

From where did 1/24 come?

Ravi said:   2 decades ago
The highest among the denominators is 24..so multiply the ratios by 24..
24/6:24/8:24/24
4:3:1

It is simple, A's share is (4/8)*3200

B's share is (3/8)*3200

C's share is (1/8)*3200
