Question

At what rate of percent per annum will the annual interst on Rs 1250 be the same as the annual interest on Rs 1500 at 8 percent per annum​

Answer 1

Answer:

Here is your answer...

Given is Time = 2 years

Amount=1800 Principal = 1250

Rate = ?

The formula to calculate amount is

=A = P(1 + R/100)^T =1800 = 1250 × (1+ R/100)^2

=1800/1250 = (1+ R/100)^2

=√(36/25) = 1+ R/100

= 6/5 - 1 R/100

=1/5 x 100 = R

= 20 = R

Therefore, the rate is 20%.
