Amit and Brijesh started a business with initial investments in the ratio of 12: 11 and their annual profits were in the ratio of 4: 1. If Amit invested the money for 11 months, then for what time Brijesh invested the money?

A) 9 months

B) 3 months

C) 5 months

D) 10 months

Correct Answer: B

Solution :

Let investment of Amit \[=12\,\,x\]

and investment of Brijesh \[=11\,\,x\]

Let Brijesh invested the money for/months.

Then, Amit's investment: Brijesh's investment

\[=\,\,(12x\times 11):(11x\times y)\]

\[=132\,\,x:11\,\,xy=12:y\]

\[\therefore \] \[\frac{12}{y}=\frac{4}{1}\] [since, ratio of profit is 4 :1]

\[\Rightarrow 4y=12\]

\[\therefore \] \[y=\frac{12}{4}=3\,\,\text{month}\]

Clearly, Brijesh invested money for 3 months.
