◍ Here, the question has given us the principal, rate of interest and time that is Rs. 2,400, 15% per annum and for 3 years respectively. Now, the question has asked us to find the simple interest of it. So to get the amount first of all we need to find out the simple interest for that we simply have to apply the formula of SI. After it we have to add the principal and the SI to get the amount.

ANSWER:-

◈ Simple Interest = Rs. 1,080

◈ Amount = Rs. 3,480

GIVEN:-

☆ Principal = Rs. 2,400

☆ Rate of Interest = 15% per annum

☆ Time = 3 years

TO FIND:-

↠Simple Interest= ?

↠Amount = ?

FORMULA:-

➾ Simple Interest = P × R × T / 100

➾ Amount = Principal + SI

SOLVING BY APPLYING THE FORMULA:-

☆ Principal = Rs. 2,400

☆ Rate of Interest = 15% per annum

☆ Time = 3 years

➾ Simple Interest = P × R × T / 100

➾ Amount = Principal + SI

• Finding the SI:-

➢ SI = 2,400 × 15 × 3 / 100

➢ SI = 2,400 × 45 / 100

➢ Cancelling the zeros.

➢ SI = 24 × 45 / 1

➢ SI = 24 × 45

➢ SI = 24 × 45 = 1,080

➢ SI = Rs. 1,080

The simple interest is of Rs. 1,080.

• Finding the amount:-

➢ Amount = 2,400 + 1,080

➢ Amount = 2,400 + 1,080 = 3,480

➢ Amount = Rs. 3,480

Thus, we got the answer. The amount is Rs. 3,480.
