Answer:
100 rs
Step-by-step explanation:
As we know that
A can do a work in = x days
B = 2x days
C = 5 days
it means
A can do a work in 1 day and b in 3 days and c in 5 days
then efficiency of them is
A = 15 unit per day
B = 5 unit per day
C = 3 unit per day (by lcm)
now
15x+5x+3x = 460
23x = 460
x = 20
so B = 5(20)
=> 100 RS answer
