Question

A man spends 65% of his salary and saves Rs. 525 per month. Find his monthly salary.

Answer 1

Solution:

Let X ₹ be the monthly salary of the person.

He spends 65% of his salary.

SAVINGS PERCENTAGE
= X - 65X/100

=35 X /100

HE SAVES 525 PER MONTH

SO,
525= 35X/100

525×100=35x

X=525×100/35

X=15x100
X=1500 ₹

So his monthly salary is 1500 ₹

Answer 2

In order to find out. First of all assume that total amount is  "X " and from the data given we know that he saves 525 after spending 65% 
So 100- 65= 35 %which is saving percentage .
So that salary will be 35X/100
because the saving amount is known
Hence, 525= 35X/100
by calculation 525*100/35 =X
So , 52500/35 = X 
And X = 1500 Rupees.
So the salary of that man will be 1500 rupees.
