Answer 1

Answer:

4%

Step-by-step explanation:

P = 7500, n = 2 years.

Given That difference between C.I and S.I = 12.

⇒ [P(1 + R)² - P] -PnR = 12

⇒ 7500(1 + R)² - 7500 - 7500 * 2R = 12

⇒ 7500[(1 + R)² - 1 - 2R] = 12

⇒ 7500[1 + R² + 2R - 1 - 2R] = 12

⇒ 7500[R²] = 12

⇒ R² = 0.0016

⇒ R = 0.04

Then:

⇒ R/100 = 0.04

⇒ R = 0.04 * 100

⇒ R = 4%

Therefore, Rate of interest = 4%.
