1. A and B started a business investing amounts in the ratio of 2 : 3. If A has invested an additional amount of Rs. 10000, their ratio of investment would have been 3 : 2. The amount invested by A was ?

A. Rs. 8000

B. Rs. 12000

C. Rs. 18000

D. Rs. 20000

Solution:

Initial ratio of investments by A and B = 2 : 3
Let their respective investments are 2x and 3x
According to the question,
If A added Rs. 10000 to his investment
Then the new ratio = 3 : 2

\begin{aligned} \Rightarrow \frac{2 x + 10000}{3 x} = \frac{3}{2} \\ \Rightarrow 4 x + 20000 = 9 x \\ \Rightarrow 5 x = 20000 \\ \Rightarrow x = 4000 \end{aligned}

Original investment by A = 2 × 4000 = Rs. 8000
