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?
Answer & explanation
Correct answer: option 2
A = 10 days, B = 15 days,

⇒ Amount for total work = Rs. 1250
⇒ Share of A & B = Total Efficiency = Total amount.
⇒ (3 + 2)x = 1250
⇒ 5x =1250
⇒ x =\(\frac{1250}{5}\) = 250.
⇒ B's share = 2 x 250 = Rs. 500 ..(Total Efficiency = Total amount)
