on car fuel. If he spends 10% of his remaining salary on food and saves the rest, then What will be the monthly salary of the person? Given that he saves Rs.10125.Solution
ATQ, we can say that Let the monthly salary of the Arvind will be 100x Then, Expenditure on travelling and car fuel will be = 30% + 25%= 55% Remaining = 100 x (55/100) x (100x) = 100x – 55x = 45x (45x) x (90/100) = 10125 x = 250 hence, the monthly salary of the Arvind will be = (100x) = (100 x 250) =Rs.25000
