Question

A and B can do a piece of work in 50 days and 40
days, respectively. If together they earned 450 by
completing the work, then what is the share of B?​

Answer 1

Step-by-step explanation:

A can complete the work in 50 days.

So, A's 1 day work = 1/50

B can complete the same work in 40 days.

So, B's 1 day work = 1/40

Ratio of their wages = 1/50 : 1/40

= 1/50 ÷ 1/40

= 1/50 × 40

= 4/5

= 4 : 5

Sum of the terms of ratio = 4 + 5

= 9

Total money earned by them by completing the work together = Rs. 450

Therefore, B's share = 450/9 × 5

= Rs. 250

Hope it helps :)

Anyways, I think this question is from class 8 Pearson.
