Given,

A + B = 2C ----(i)

C + D = 2A----(ii)

Adding (i) and (ii) we get : A + B + C + D = 2C + 2A  

=>  B + D = A + C

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+5*10*x100=3,500,000-x+12.5*10*3,500,000-x100

 x+50x=3,500,000-x+125100*3,500,000-125x100

 2x+50x100+125x100=3,500,000*1+54

 200x+50x+125x100=94*3,500,000

 =>x=2,100,000=21 lakhs
