Find sum of money when a Percentage of such sum is given

Question 1

A man has a certain unknown sum of money, 60 % of that sum is ₹ 4800. What is the sum of money?

Explanation:

The problem can be solved using linear equation.
Let the unknown sum of money be ₹ a
We know, that 60 % of ₹ a = ₹ 4800

60 % x a = ₹ ( 4800 )
60/100 x a = ₹ ( 4800 )

a = ₹ (4800 x 100)/60

= ₹ 8000
Therefore, the unknown sum of money available with the man is ₹ 8000
