Question

At what rate percent per annum will interest on Rs. 1305 amount to Rs. 1740 in 4 months?
​

Answer 1

Answer:

Rate = 100% per annum.

Step-by-step explanation:

principal = Rs. 1305

Amount = Rs. 1740

Simple interest = ?

Then,

Simple interest = 1740 - 1305 = Rs.435

And Then,

principal = Rs. 1305, Simple interest = Rs. 435,

Time = 4 months = 4/12 years = 1/3 years.

Rate = SI × 100 / P × T

= 435 × 100 / 1305 × 1/3

= 100% per annum ( ans. )
