উত্তর:
Tk. 6,000
Money spent on books = 1/3
Money spent on clothing = 1/2 x (1 - 1/3) = 1/2 x 2/3 = 1/3
Money spent on food = 3/4 x {1 - (1/3 + 1/3)} = 3/4 x (1 - 2/3) = 3/4 x 1/3 = 1/4
Fraction of money left over = 1 - (1/3 + 1/3 + 1/4) = 1 - (4 + 4 + 3)/12 = 1 - 11/12 = 1/12
Now, 1/12 th of the money = 500
So, total money she started with = 500 x 12 = 6000 TK
