A) 10 years |

B) 12 years |

C) 12.5 years |

D) 10.5 years |

Correct Answer:

C) 12.5 years |

Description for Correct answer:

According to question

\( \Large 2P = \frac{P \times 2 \times 5}{100} \)

R = 40%

At the same rate and Now, same sum becomes 6 times in t years

\( \Large 5p = \frac{P \times 40 \times t}{100} \)

\( \Large t = \frac{500}{40} Years\)

\( \Large t = \frac{25}{2} Years\)

t = 12.5 Years

Option (C)is correct.
