The price of rice is increased by 40% due to this a person can buy 6 kg less rice for Rs. 300. Find the new consumption of rice.
Answer & explanation
Correct answer: option 4
40% = \(\frac{2}{5}\)
Price ∝ \(\frac{1}{Qty.}\) {When expenditure is constant}
Therefore,
Old : New
Price : 5 : 3
Qty. : 3 : 5 ⇒ 2R (difference)
ATQ,
2R = 12 kg
So, New Consumption = 5R = 5× 6 = 30 kg.
