Correct Answer: 240
Solution:
A's 1 day work=1/12
B's 1 day work=1/15
let c's 1 day work=1/x
now With the help of C, they altogether completed in 5 days, i.e 1/12+1/15+1/x=1/5
by solving we will get 1/x=1/20
now A 's 1 day work:B's 1 day work:C's 1 day work=1/12:1/15:1/20=5:4:3
Now the C's share=\(\frac{3}{5+4+3}*960=240\)
hence the answer is 240 rupees
