Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. 35 years.

The time when the simple interest equals the principal :

⇒ T = 100R\frac{100}{R}

and R = 2672\frac{6}{7} or 207\frac{20}{7}

Hence T = 100207\frac{100}{\frac{20}{7}}

⇒ T = 100 × 720\frac{7}{20}

⇒ T = 35 years
