A Correct answer
Explanation

Let Ankita's total money be x. She spends 37.5% on rent, so remaining = 62.5% of x = 5x/8. She then spends 40% of remaining on food: 40% of 5x/8 = x/4. Money left for sons = 5x/8 - x/4 = 3x/8. This is divided in ratio 12:13, so difference = (13-12)/(12+13) × 3x/8 = 3x/200 = 60. Thus x = Rs. 4000.
