Question

A, B and C can do a work in x, 3x and 5x days respectively. They worked together and earned Rs 460.
What is the share of B?
​

Answer 1

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
