Question

find the amount to be paid at the end of three years in the below case
a) Principal= 1200 Rs at 12% p.a.​

Answer 1

Solution!!

The concept of simple interest has to be used here. The principal, rate of interest and time is given in the question. We have to find the amount. To do so, we have to find the simple interest.

Principal (P) = Rs 1200

Rate of interest (R) = 12%

Time (T) = 3 years

Let's find the simple interest!!

Interest = (P × R × T)/100

Interest = (1200 × 12 × 3)/100

Interest = 12 × 12 × 3

Interest = Rs 432

Now that we know the interest, we can easily find out the amount.

Amount = Principal + Interest

Amount = Rs 1200 + Rs 432

Amount = Rs 1632

Hence, the amount is Rs 1632.

Answer 2

Answer:

p = 1200 rupees

time = 3 years

rate = 12%

SI = p×t×r÷ 100 1200 x 3 x 12 ÷ 100

= 432 rupees

p + SI = 1200 + 432 = 1632 rupees
