- 20 Rs.
1 day work of Man=1/10, If Boy's 1 day work=1/x, then
(1/10)+(1/x)=1/6, x=15
Ratio of work of Man & Boy=1/10:1/15=3:2
So out of 50 Rs. Boy's share=2*50/(3+2)=20 - 10 years agoHelpfull: Yes(45) No(4)
- 20 is the wrong answer.
50 rupees is not toatal share..its only share of 1st persion. findout the total share , and then use 2/5*total share. - 10 years agoHelpfull: Yes(13) No(15)
- 20.
Let boy complete work in b days.
Man one day work 1/10
Boy one day work 1/b
So the equation form
(1/10) + (1/b) = (1/6)
From this b = 15days
Work done in one day is in 3:2 proportion so boys share is 20. - 10 years agoHelpfull: Yes(7) No(2)
- M = 1/10,M+B = 1/6 SO B=1/6-1/10=1/15
SO M:B = 2:3
Boys share is 3/5*50 =30RS - 10 years agoHelpfull: Yes(3) No(11)
- 20 Rs.
man can do work in 10 days
man + boy can do a work in =6 days
so work done by man in 1 day is 6
and work done by boy in 1 day is 4.
so share of boy will be (4/10) * 50= 20 Rs. - 10 years agoHelpfull: Yes(1) No(3)
