(ASRE 2024)

(A) 12·5%

(B) 15%

(C) 13%

(D) 14·5%

Answer:- (C) ₹10

Solution:- 

Simple Interest Formula:

Simple Interest = (Principal × Rate × Time) / 100

Given:

• Principal (P) = ₹10
• Rate (R) = 10% per year
• Time (T) = 10 years

Calculation:

Simple Interest = (10 × 10 × 10) / 100
Simple Interest = 1000 / 100
Simple Interest = ₹10

Therefore, the total interest accrued is ₹10.
