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

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

A efficiency 16.66.

B efficiency 12.50.

So total work of A+B is 29.16 remaining 70.84.

So 70.84/3 = 24(C efficency )

1/6 : 1/8 : 1/24 and ratio 4:3:1.

Answer above says highest number is 24 so multiply all by 24... is that the logic?

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.

I think this is a wrong question. In it the information is not given that for how many days A and B are given 3200?

SAI SRI said:   9 years ago
A's SHARE =3/6*3200 = 1600.
B's SHARE =3/8*3200 = 1200.

TOTAL A & B =1600+1200 = 2800.
C's SHARE =3200-2800 = 400.

3*1/24*3200.
How it come, normally we add all the ratio and the ratio is 4:3:1.

How I find the share of A and B?

Keerthu said:   1 year ago
A + B + C = 1/3.
A + B = 1/6 + 1/8 = 7/24,
C = 1/3 - 7/24 = 1/24,
C's share 3 days of work = 3 * 3200/24 = 400.

If both a and b work together on the single piece than in how many days they will complete their work and how?

Ved Prakash Singh said:   8 years ago
C's one day work=1/24.
so C's 3 days work is=1/8.
C will take 1/8 part of 3200 which is equal to 1/8*3200=400.
