A. Rs. 16000 B. Rs. 20000 C. Rs. 24000 D. Rs. 28000 Answer: Option DShow Answer
Solution(By Apex Team)
Suppose B invested Rs. x for y months
Then, A invested Rs. 3x for 2y months
$\begin{array}{l}
\text { So, A : B } \\
=(3 x \times 2 y):(x \times y) \\
=6 x y: x y \\
=6: 1
\end{array}$
$\begin{array}{l}\therefore\text{B’;s profit : Total profit}\\
=1\ :\ 7\\
\text{Let the total profit is Rs. x}\\
\text{Then,}\\
\Large\frac{1}{7}=\frac{4000}{x}\\
\Rightarrow x=28000\end{array}$
