Answer 1

A one day work = 1\20
B one day work =1/30
A+ b one day work =1\20+1/30
=5/60
=1/12
With c they can do it in 8 days,
1/12*8
=1/6
So with c they can do it in 6 days

Answer 2

Answer:

rs. 30, rs.20, rs.25

Step-by-step explanation:

Everybody will get the wages according to their labour.

A’s one day work = 1/20;

A’s 8 days work = 8/20 = 2/5 ;

B’s one day work = 1/30 ;

B’s 8 days work = 8/30 = 4/15 ;

Remaining work = 1- 2/5 - 4/15 = 1/3 ;

C did the work in 8 days = 1/3.

wages are divided in the ratio of 2/5 : 4/15 :1/3 = 6 : 4 : 5 ,

A’s share = 6/15* 75= 30 Rs.

B’s share = 4/15* 75 = 20 Rs.

C’s share = 5/15* 75 = 25 Rs.
