Question
A girl spent 30% of her monthly income on clothing. Of
the remaining, she spent on travel and food in the ratio of 4:3. If the difference of the income spent on travel and food is Rs.612, then find her monthly income.Solution
Let her income be 100%. Remaining income = (100 - 30)% = 70% Let the money spent on travel and food be Rs. 4x and Rs. 3x respectively. Now, according to question, => 4x – 3x = 612 => x = 612 Total money spent on travel and food together = 7x = 4284 => 70% --- 4284 => 100% ----- 6120 Therefore her income is Rs. 6120.
