Question

A, B and C can do a work in 7 , 14 and 21 days respectively. They completed the work and got Rs.363. What is the share of C?

Answer 1

Answer:

we find ratio of working speed of A,B,C which is 7:14:21 = 1:2:3

total money = 363 Rs

money share should be in same proportion as working speed

so ratio of money = 3:2:1

let ratio is x

so total money = x+2x+3x= 363

6x=363

x= 363/6=121/2

share of C = x= 60.5 rs

pls mark that we change ratio while taking for money because faser one will work get more money
