Question
Out of his total monthly salary, a man spends 20% on
transportation and 40% on food. Out of the remaining salary, he spends 10% on fuel and saves the rest which is equal to Rs.18,000. Find his monthly salary.Solution
Let the monthly salary be Rs. '100x'. Amount spent on transportation = 100 X 0.2 = Rs. '20x' Amount spent on food = 100 X 0.4 = Rs. '40x' Amount spent on fuel = (100x - 20x - 40x) X 0.1 = Rs. '4x' So, savings = 100x - 20x - 40x - 5x = Rs. '36x' ATQ, 36x = 18,000 So, 'x' = 500 So, required monthly salary will be = Rs.100x = Rs. (100 X 500) = Rs.50,000
