MCQ
A and B started a business with a total capital of  30,000. At the end of the year, they shared the profit in the ratio of their investments. If their capitals were interchanged, then A would have received 175% more than what he actually received. Find out the capital of B.

• ₹ 20,000

• ₹ 22,000

• ₹ 21,000

• ₹ 23,000

#### Solution

₹ 22,000

Explanation:

Let A contributed x and B (30000−x)

then in Ratio, they will get profit="x"/(30000-"x")

when Ratio is exchanged i.e.=(30000-"x")/"x"

ATQ

(30000-"x")-"x"=175/100"x"

30000-2"x"=175/100"x"

30000=175/100"x"+2"x"

30000=375/100"x"`

8000 = x

30000 − x =30000 − 8000

= 22000
