Lucky spends 85% of her income. If the expenditure by x % savings increase by 60% and income increases by 26% , then what is the value of x ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 20
Let the income of lucky be 100x
increased income = 126x
Expenditure of lucky = 85x
Saving = 15x
15x × 8/5 = 24x
expenditure = 126x - 24x = 102x
Increase in expenditure = 102x - 85x = 17x
percentage increased = (17x/85x) × 100 = 20%
