Answer 2

Answer:

1. 12.5 years or 12 1/2 years

Step-by-step explanation:

Rate (R) % = 10% p.a.

Let Principal (P) be ₹ 100 and Time be T

Amount = 2.25 times the Principal = 2.25 × 100 = ₹ 225

SI = Amount - Principal = ₹(225-100) = ₹ 125

SI = PRT/100

125 = 100 * 10 *T/100

125 * 100/100 * 10 = T

Hence,

T = 12.5
