Question

Nupur credits $15\%$ of her salary to her fixed deposit account and spends $30\%$ of the remaining amount on groceries. If the cash in hand is Rs. $2380$, what is her salary?

• A. Rs. $3500$
• B. Rs. $4000$
• C. Rs. $4500$
• D. Rs. $5000$

Answer 1

The correct option is B Rs. $4000$

Let's assume salary of nupur $=x$
$15\%$ on fixed deposit
remaining $x-x\times \frac{15}{100}=x-0.15x=0.85x$
30% of the remaining amount on groceries
Cash=$0.85x-0.85\times \frac{30}{100}x=0.85x-0.255x=0.595x$
$2380=0.595x$
$x=4000$
Answer (B) 4000
