A) 17.5 lakhs | B) 21 lakhs |

C) 15 lakhs | D) 20 lakhs |

Explanation:

Let Rs.x be the amount that the elder daughter got at the time of the will. Therefore, the younger daughter got (3,500,000 - x).

The elder daughter’s money earns interest for (21 - 16) = 5 years @ 10% p.a simple interest.

The younger daughter’s money earns interest for (21 - 8.5) = 12.5 years @ 10% p.a simple interest.

As the sum of money that each of the daughters get when they are 21 is the same,

$x+\frac{5*10*x}{100}=\left(3,500,000-x\right)+\frac{12.5*10*\left(3,500,000-x\right)}{100}$

$x+\frac{50}{x}=3,500,000-x+\frac{125}{100}*3,500,000-\frac{125x}{100}$

$2x+\frac{50x}{100}+\frac{125x}{100}=3,500,000*\left(1+\frac{5}{4}\right)$

$\frac{200x+50x+125x}{100}=\frac{9}{4}*\left(3,500,000\right)$

=>$x=2,100,000=21lakhs$
