The price of rice is increased by 20% due to this a person can buy 12 kg less rice for Rs. 300. Find the new consumption of rice.
Answer & explanation
Correct answer: option 2
20% = \(\frac{1}{5}\)
Price ∝ \(\frac{1}{Qty.}\) {When expenditure is constant}
Therefore,
Old : New
Price : 5 : 6
Qty. : 6 : 5 ⇒ 1R (difference)
ATQ,
1R = 12 kg
So, New Consumption = 5R = 5× 12 = 60 kg.
