QUESTION:

A man saved rupees 500 in his saving account per month and spends 80% of his salary. Find his monthly salary.

SOLUTION:

Let monthly salary be Rs. X

According to question,

expenditure = 80% of X

$\\ \\ \\ = \frac{80}{100} x \\ \\ \\ x = \frac{4}{5} x$

we know that,

Savings = income - expenditure

$\\ \\ \\ \\ savings = x - \frac{4x}{5} \\ \\ \\ = \frac{5x - 4x}{5} \\ \\ \\ = \frac{x}{5} \\ \\ \\ \\ saving \: amount \: = 500(given) \\ \\ \\atq : \\ \\ \\ \\ = > \frac{x}{5} = 500 \\ \\ \\ x = 5 \times 500 = 2500 \: rs$
