B invests 30% of his monthly salary on Travelling and 20% of remaining on Food. Again, he invested 25% of the remaining (after travelling and food expenses) on Rent. If he invested Rs. 8,400 on Rent and Food, then find his monthly salary.
Let monthly salary of B = 100x Amount invested on Travelling = (30/100) × 100x = 30x Remaining amount = 100x – 30x = 70x Amount invested on Food = (20/100) × 70x = 14x Remaining amount = 70x – 14x = 56x Amount invested on Rent = (25/100) × 56x = 14x ATQ, => (14x + 14x) = 8400 => x = 300 Therefore, monthly salary of B = 100 × 300 = Rs. 30,000
