Question

The monthly income of a man is Rs. $16,000$. $15$ percent of it is paid as income-tax and $75\%$ of the remainder is spent on rent, food, clothing, etc. How much money is still left with the man ?

• A. Rs. $3,800$
• B. Rs. $3,700$
• C. Rs. $4,000$
• D. Rs. $3,400$

Answer 1

Answer: (D)

Rs. $3,400$

Since $15\%$ of the income is paid as income-tax, $100-15=85\%$ of the income is left with him.
Since $75\%$ of this remaining $85\%$ money is spent, he will still have $100-75=25\%$ of the $85\%$ of the income
Hence
$25\%$ of $85\%$ of $16,000=\frac{25}{100}\times \frac{85}{100}\times 16,000=Rs3,400$
Hence, $Rs3,400$ is still left with the man
