Q:

A) Rate = 7% and Time = 7 years. | B) Rate = 8% and Time = 8 years. |

C) Rate = 6% and Time = 6 years. | D) Rate = 5% and Time = 5 years. |

Answer: B) Rate = 8% and Time = 8 years.

Explanation:

Explanation:

Let sum = X. Then S.I = 16x/25

Let rate = R% and Time = R years.

Therefore, (x * R * R)/100 = 16x/25 => R = 40/5 = 8

Therefore, Rate = 8% and Time = 8 years.
