if the lady's b'day was in the leap year....
then the time (in yrs) for which lady invested rs250/- = (60-20)/4 = 10 yrs ( bcz leap yr comes aftr every 4 yrs)
her invested amount in 10 yrs=10*250= RS 2500/-
and if her brother's b'day falls every year, and each year he takes RS 50/- from the piggy bank, then in (60-20) =40 years he took out the amount of RS 50*40 =RS 2000/-.........
then of course the remaining money in the piggy bank is RS(2500-2000)/- = RS 500/-.....
so simple..... :)
