Question

simple interest on rs 4000at the rate of 5 %per annum for 2 years is​

Answer 1

Solution!!

Given:-

→ Principal (P) = Rs 4000

→ Rate of interest (R) = 5%

→ Time (T) = 2 years

Formula:-

→ $\sf Interest=\dfrac{P\times R\times T}{100}$

Putting the values, we get

→ $\sf Interest=\dfrac{40\cancel{00}\times 5\times 2}{1\cancel{00}}$

→ Interest = 40 × 5 × 2

→ Interest = Rs 400

You just have to remember the formula used above. If the interest is given and you have to find out the principal or time or rate of interest, you can use the same formula to find it. The questioner may also ask to find out the amount.

Amount = Principal + Interest

You can use this formula to find out the amount.
