A alone can complete a work in 12 days and B alone can complete the same work in 15 days. If they finish the work together and received Rs. 3600. Then find the share of A.

A
Rs. 1200

B
Rs. 3000

C
Rs. 1500

D
Rs. 2000

Solution

Given,

A alone can complete a work in = 12 days

B alone can complete the same work in = 15 days

As we know,

Wages are distributed into efficiency ratio.

Efficiency is inversely proportional to time.

Time ratio of A and B = 12 : 15 = 4 : 5

Efficiency ratio of A and B = 5 : 4

According to the question,

5 + 4 = 9 units

⇒ 9 units = 3600

⇒ 1 unit = 400

⇒ 5 units = 5 × 400 = Rs. 2000

∴ Share of A is Rs. 2000.✅
