Question
A girl spent 20% of her monthly income on clothing. Of
the remaining, she spent on travel and food in the ratio of 3:2. If the difference of the income spent on travel and food is Rs.512, then find her monthly income.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.
