Question:

In how many years does the sum of ₹ 1,200 become ₹ 1,800 at the rate of simple interest of 5% per annum?

Answer :

Given:

P = 1,200

A= 1,800

R= 5

T= ?

To find : = Number of years

Step 1 :

SI = ?

Amount = Principal + Interest

1,800= 1,200 + ?

$= 1800 - 1200 = 600$

Interest = 600

Step 2:

$T = \frac{ I \times 100 }{P \times R} \\ = \frac{600 \times 100}{1200 \times 5} \\ = 10$

Hence, no. of yrs = 10 years
