Question
A girl spent 10% of her monthly income on clothing. Of
the remaining, she spent on travel and food in the ratio of 5:4. 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 - 10)% = 90% Let the money spent on travel and food be Rs. 5x and Rs. 4x respectively. Now, according to question, => 5x – 4x = 512 => x = 512 Total money spent on travel and food together = 9x = 4608 => 90% --- 4608 => 100% ----- 5120 Therefore her income is Rs. 5120.
