Correct Answer: (1)
Solution: (1)
Let Dhiren’s monthly salary be Rs. 100 .
Investment in mutual fund $=$ Rs. 30
Expenditure on house rent $=\frac{70 \times 20}{100}=$ Rs. 14
$\therefore$ Expenditure on grocery $=$ Rs. 24
Expenditure on medicine $=$ Rs. 16
Savings $=100-(30+14+24+16) = Rs. (100-84)$ $=$Rs. 16
When savings is Rs. 16 , monthly salary $=$ Rs. 100
When savings is Rs. 4400,
monthly salary $=$ Rs. $\left(\frac{100}{16} \times 4400\right)$ $=$ Rs. 27500
