    C Rs.3120 Correct Answer Incorrect Answer
    D Rs.3200 Correct Answer Incorrect Answer

    Solution

    Let her income be 100%. Remaining income = (100 - 20)% = 80% Let the money spent on travel and food be Rs. 3x and Rs. 2x respectively. Now, according to question, => 3x – 2x = 512 => x = 512 Total money spent on travel and food together = 5x = 2560 => 80% --- 2560 => 100% ----- 3200 Therefore her income is Rs. 3200.
