Correct Answer: Rs. 96000
Solution : Let the total income be 100 units. Remaining amount after spending = 100 – (25 + 15 + 45) = 15 units According to the question, 15 units = Rs. 14400 1 unit = $\frac{14400}{15}$ Then, total income = 100 units = $100×\frac{14400}{15}$ = Rs. 96000 Hence, the correct answer is Rs. 96000.
