Question

Ram spends $40$% of his salary on food, $20$% on house rent, $10$% on entertainment and $10$% on conveyance. If his savings at the end of a month are Rs. $1500$, then his salary per month (in Rs) is:

Answer 1

Let his total salary be $Rs.x$ ( monthly)

$\frac{40}{100}x+\frac{20}{100}x+\frac{10}{100}x+\frac{10}{100}x=1500$

$\frac{80}{100}x=1500$

$x=\frac{150\times 100}{8}=75\times 25$

$x=1875$
