Question

the simple interest on a sum of money is 25% of the principal and the number of year is equal to the rate percent per annum. Find the rate​

Answer 1

hEYA MATE!!! HERE IS YOUR ANSWER

As given, simple interest(SI) is 25% of principal(P) and number of year(T) is equal to the rate(R) of percent.

Therefore

SI = 25 % of P

T = R

As we know SI = P * R * T / 100

So we have

25%of p = p * r * t /100

25/100 * P = PR^2/100

R^2 = 25

R = 5

Hence, Rate is 5 %

Have a good day ahead mate!!!
