If the difference between CI and SI principal of Rs. 25000 for 2 years is Rs. 6250. Find the rate of interest?1. 10%2. 20%3. 50%4. 30%

Answer» Correct Answer - Option 3 : 50%

Given:

The difference between CI and SI for 2 years = 6250

Principal = 25000

Concept used:

The difference between CI and SI for 2 years = P(R/100)2

Calculation:

25000 × (R/100)2 = 6250

⇒ R2/100 = 25

⇒ R2 = 2500

⇒ R = √2500

⇒ R = 50%

∴ Rate of interest is 50%
