Question:
Rohit deposits 12% of his income in a bank. He deposited Rs 1440 in the bank during 1997. What was his total income for the year 1997?
Solution:
Let the total income for the year 1997 be Rs $x$.
i.e., $12 \%$ of $x=1440$
$\Rightarrow \frac{12}{100} x=1440$
$\Rightarrow x=\frac{144000}{12}$
$\Rightarrow x=12000$
$\therefore$ Rohit's total income was Rs 12,000 .
