A person spends 40$\%$ of his salary on his educational expenses. He spends 60$\%$ of it in purchasing books and one-half of the remaining in purchasing stationery items. If he saves Rs 160 every month, which, is one-fourth of the balance after spending over books and stationery items, what is his monthly salary?

• D. Data indadequate

Answer 1

Answer: (A)

Rs 8,000

Answer 2

Let the person's salary be $x$
He spends on education $=0.4x$
books $=0.24x$
Stationary items $=\frac{(0.4-0.24)x}{2}$
$=0.08x$
Remaining amount $=0.4x-(0.24x-0.08x)=0.08x$
According to question
$\frac{1}{4}\times0.08x=160$
$\therefore$ $x-\frac{160\times4}{0.08}=Rs 8000$
The correct option is (A)
