A and B can complete a work in 10 days and 15 days, respectively. They got a total of Rs. 1,250 for that work. What will be B’s share?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. Rs. 500.
Given:
A can complete a certain work in = 10 days
B can complete a certain work in = 15 days
We know that,
Work done = Efficiency × Time taken
The wages are distributed in the ratio of the respective efficiency.
Now,
Let the total work be LCM(10, 15) = 30
The efficiency of A = 30/10 = 3
The efficiency of B = 30/15 = 2
They got a total of Rs. 1,250 for that work.
So, the share of B =1250 × 2/5
⇒ 250 × 2 = Rs. 500
Hence the share of B is Rs. 500.
