Answer 1

Answer:

Explanation:

Work done by A in one day = 1/6

Work done by B in one day = 1/8

Work done by C in one day  =A+B+C=1/3  

1/6+1/8+C=1/3  

C=1/3−1/6−1/8  

C=1/3−7/24=1/24  

i.e, C alone can finish the same work in 24 days

Percentage of involvement of C to complete the work is,

Work done by C in oneday /  Work done by combiningA,B,C in one day∗100  

 

=  12413∗100=324∗100= 12.5 %

Then, amount to be paid to C is  12.5 % of  3200 ,

12.5100∗3200=400  

Hence, option B is correct
