Question
Out of her total income, Meena spent 15% on groceries,
25% on food and 10% on transport. If she spent 30% of the remaining on entertainment and saved the rest which is Rs. 1,400, then find her total income.Solution
Let total income of Meena be Rs. '100x' So, amount left after she spent part of it on groceries, food and transport = 100x - (0.15 + 0.25 + 0.10) X 100x = Rs. '50x' So, 0.70 X 50x = 1,400 Or, x = (1400/35) = 40 So, total income of Meena = 100x = 100 X 40 = Rs. 4,000 Hence, option d.
