Question

Sonali invests $15\%$ of her monthly salary in insurance policies. She spends $55\%$ of her monthly salary on shopping and household expenses. She saves the remaining amount of Rs. $12,750$. What is Sonali's monthly income?

• A. Rs. $42,500$
• B. Rs. $38,800$
• C. Rs. $40,000$
• D. Rs. $35,500$

Answer 1

The correct option is A Rs. $42,500$

Let the total amount be $x$.

Insurance $=15\%$

Shopping $+$ household $=55\%$

Thus, the invested percentage is $15+55=70\%$.

$30\%$ is the remaining amount.

According to the problem, Sonali saves Rs. $12,750$.

Therefore, $30\%$ of $x$ $=12750$

$\Rightarrow \frac{30}{100}\times x=12750$

$\Rightarrow x=42500$

Thus, the monthly income of Sonali is Rs. $42500$.
