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?
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 |

1/6 * 24 : 1/8 * 24 :1/24 * 24 convert fraction to the whole number.

Ratio = 4:3:1.
4x3x + x = 3200.
8x = 3200,
X = 400,
C's share = 400.
4x3x + x = 3200.
8x = 3200,
X = 400,
C's share = 400.

You can directly write there 4x+3x+x=3200, then you also got x=400.
