Answer 2

The Rs.1125 is the sum of money that will amount to Rs.1800.

Given,

Amount = Rs.1800

Time = 5 years

Rate of interest = 12% p.a.

To Find,

Principal on the given amount.

Solution,

Let the principal be x.

We will use the formula:

= $\frac{p*r*t}{100}$

= x ×(100 + 12 × 5)/100

= x × (100 +60)/100

= x × 160/100

= 1.6 x

Amount = Rs.1800

x = $\frac{1800}{1.6}$

x = Rs.1125

Principal = Rs.1125

The Rs.1125 is the sum of money that will amount to Rs.1800.
