Answer 2

Given - Amount, rate of interest, time

Find - Principal

Solution - The sum of money is 10000.

Let the principal be x. Firstly finding the interest.

Interest can be calculated using the formula = Principal*rate of time*interest/100

Interest = x*4*5/100

Performing multiplication to find the value of interest.

Interest = 20x/100

Performing division to find the value of interest.

Interest = x/5

Now, finding the principal from the given formula - Amount = Principal + Interest

12000 = x + x/5

Performing addition to find the value of x

12000 = 5x + x/5

Performing multiplication and then division to find the value of x.

12000*5 = 6x

6x = 60000

x = 10000

So, the sum of money is 10000.
