The total consumption of sugar was 20 kg per month for a family. As the price of sugar increased by 35%, the family reduced its consumption so that the expenditure on sugar increased only by 8%. By how much was the consumption of sugar per month reduced due to an increase in the price of sugar?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 4 kg.
Let original price = ₹1 per kg
Original consumption = 20 kg
⇒ Original expenditure = ₹20
New price = ₹1 + 35% = ₹1.35 per kg
New expenditure = ₹20 + 8% = ₹21.60
New consumption = = 16 kg
Reduction in consumption = 20 – 16 = 4 kg
