Answers
A works in 15 days and B in 20 days.
One day work of A=1/15
One day work of A=1/20
Together One day work = 1/15 + 1/20 = 35/300 =7/60
A and B together complete the work in 60/7 days
With C’s help, work is done in 3 days less time.
A, B and C together to complete 60/7 -3=39/7 days
All together one day work (A + B + C) =7/39
Therefore one day work of C t =7/39 -7/60 =140/780 - 91/780 =49/780
complete work by C alone 780/49=16 days
ONE DAY WORK A: B: C 1/15 :1/20 : 1/16=
They all together work in same days. 16:12:15
If their total earnings is Rs 8800.
C’s share = (15/44 ) x = Rs 3000
A works in 15 days
and B in 20 days.
1 day work of A=1/15
1 day work of A=1/20
Together 1 day work of A and = 1/15 + 1/20 = 35/300 =7/60
A and B together completes the work in 7/60 days
With C’s help, work is done in 3 days less time.
A, B and C together to complete 7/60 -3=7/39 days
All together one day work (A + B + C) =7/39
so
1 day work of C t =7/39 -7/60 =140/780 - 91/780 =49/780
complete work by C alone 780/49=16 days
1 day work A: B: C 1/15 :1/20 : 1/16=
They all together work in same days. 16:12:15
If their total earnings is Rs 8800.
then
C’s share = (15/44 ) x = Rs 3000 answer
