Question

:A father leaves Rs 506400 to his son and daughter, in such a
way that the share of each, when he/she becomes 20 years old, is
the same. If Simple Interest is calculated at 5 p.c.p.a, and if the
ages of the boy when the father died is 18 and that of the girl is
16, find the sum which the father leaves to each

Answer 1

Let boy gets x then girl would get

(506400-x) Now for boy on Ex the ROI of 5 p.c.p.a

would be calculated for 2 years and for gal on (506400-x) the ROI of 5 p.c.p.a would be calculated for 4 years. However both are equal.

So mathematically

x*5*2= (506400-x) *5*4

=> x = 2 (506400-x)

=> 3x=2* 506400

=> x = 337600 share of boy

and shares of gal = 168800.
