A family spends ₹240 per month to buy sugar. A rise of 25% in the price of sugar compels the family to reduce the monthly consumption of sugar by 1.5 kg as it decides to spend the same amount of money on purchase of the commodity. What is the increased price per kg of sugar?
Answer & explanation
Correct answer: option 3
Price ∝ \(\frac{1}{consumption }\)
25% = \(\frac{1}{4}\)
Ratio of , Initial : New
Price 4 : 5
Consumption 5 : 4
According to question ,
( 5-4)R = 1.5kg
1R = 1.5 kg
4R = 1.5 × 4 = 6kg
As , Total Amount paid is same
New price of sugar = \(\frac{240}{6}\)
= 40
So , New price of sugar is 40 Rs./kg .
