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 |

Can anyone say how the 1/6+1/8 comes as 7/24?
I need the clear explanation of the solution.

Please help.
Where did the number 8 come from in 1/8*3200 = 400?
Where did the number 8 come from in 1/8*3200 = 400?

Last step can be written as C's share = 1/8*3200 = 400.

Ya The question is actually not clear. Its should say A, B and C undertook the work for Rs. 3200. The questions as it is stated may imply that A and B took Rs. 3200 individually. Correct me if I'm wrong.

See from the problem we can calculate c's 1 day work = 1/24.
It means he can complete work in 24 days.
So for calculating wage of c we can say for 24 days he is to be paid 3200. But for 3 days he is to be paid?
Cross multiply we get (3*3200) /24=400.
Its easy.

4:3:1.
C share will be simply as already we have count for 3 days work.
1/4+3+1*32000 = 1/8*3200 = 400.
Answer.

1/4+3+1*32000 = 1/8*3200 = 400.

Why we are multiply all by 24? I think C's 1 day work is 1/24 so we have to multiply all by 24 in order to get the 3 days work. Am I right?

From the ratio itself we can calculate.
A's wages:B's wages:C's wages = 4:3:1.
Then to calculate C's wages from 3200 = 1/(4+3+1) * 3200.
= 1/8 of 3200.
= 400.
A's wages:B's wages:C's wages = 4:3:1.
Then to calculate C's wages from 3200 = 1/(4+3+1) * 3200.
= 1/8 of 3200.
= 400.
