Question

A B and C can finish a piece of work in 12 days 15 days and 20 days respectively if all the three work at it together and they are paid rupees 960 for the whole work how should the money be divided among them

Answer 1

Answer:

Step-by-step explanation:

A's one days work=1/12  

B's one days work=1/15  

Assume finishes work alone in X days  

Cs one days work =1/X  

All the threes one day work =1/5  

1/12+1/15 +1/X=1/5

I/X=1/20  

Now divide 960 in ratio of wok  

i.e. 1/12:1/15:1/20  

5:4:3  

so share of each  

A's=5*960/5+4+3=400 similarly  

B's 320  

c’s240
