Question

calculate the simple interest at the end of 1 year on rs. 4000 at 5% per annum​

Answer 1

Explanation:

Given :- p= rs. 4000, r=5% , t= 1year

so, S.I = p×r×t/100

= 4000×5×1/100 = rs.200

Answer 2

Solution!!

The concept of simple interest has to be used here. The principal, rate of interest and time is given. We have to find the interest.

Principal (P) = Rs 4000

Rate of interest (R) = 5%

Time (T) = 1 years

We can find out the interest with the help of just one formula!

Interest = (P × R × T)/100

Interest = (12000 × 6 × 2)/100

Interest = Rs 1440

The questioner can also further ask you to calculate the amount. So, here's how you can find the amount.

Amount = Principal + Interest
