◍ Here, the question has given us the Simple Interest, principal and time that is Rs. 4,800, Rs. 15,000 and for 4 years respectively. Now, the question has asked us to find the rate of interest at what Rs. 15,000 earns 4,800 as simple interest in 4 years. So to get the answer we need to apply the formula of simple interest first.

★ HOW TO DO:-

◍ Here we are asked to find the rate. So, to find the rate we will use the formula of simple interest by assuming the rate as R. After that we have to solve by putting the values and the result will be the rate of interest.

------------------

ANSWER:-

◈ The rate of interest is 8%.

GIVEN:-

☆ Simple Interest = Rs. 4800

☆ Principal = Rs. 15,000

☆ Time = 4 years

TO FIND:-

↠ Rate of interest = ?

FORMULA:-

⬤ Simple Interest = P × R × T / 100 [For finding the rate of interest]

SOLVING BY APPLYING THE FORMULA:-

☆ Simple Interest = Rs. 4800

☆ Principal = Rs. 15,000

☆ Time = 4 years

⬤ Simple Interest = P × R × T / 100

• Finding the Rate of interest:-

➢ 4,800 = 15,000 × R × 4 / 100

➢ Cancelling the zeros.

➢ 4,800 = 150 × R × 4 / 1

➢ 4,800 = 150 × R × 4

➢ 4,800 = 600 × R

➢ Transposing 600 to L.H.S

➢ 4,800 / 600 = R

➢ 4,800 / 600 = 8

➢ 8 = R

➢ R = 8

Thus, we got the answer. The rate of interest is 8%.
