A man spends 30% of his monthly income on rent. Out of the remaining income, he spends 50% on travelling and saves the rest. If his savings are Rs 7000, find his monthly income (in Rs).

Explanation

​ Information Given: Rent = 30% of income Remaining = 70% of income Travelling = 50% of remaining Savings = Rs7000 Concept/Formula Used: Successive percentage Savings = Remaining income − Travelling expense Explanation: Let total income = 100x Rent = 30x Remaining = 70x Travelling = 50% of 70x = 35x Savings = 70x − 35x = 35x Given, 35x = 7000 x = 200 Monthly income = 100x = 100 × 200 = 20000 Rs
