Question
A girl spent 16% of her monthly income on clothing. Of
the remaining, she spent on travel and food in the ratio of 5:2. If the difference of the income spent on travel and food is Rs.1836, then find her monthly income.Solution
Let her income be 100%. Remaining income = (100 - 16)% = 84% Let the money spent on travel and food be Rs. 5x and Rs. 2x respectively. Now, according to question, => 5x – 2x = 1836 => x = 612 Total money spent on travel and food together = 7x = 4284 => 84% --- 4284 => 100% ----- 5100 Therefore her income is Rs. 5100.
