Question
The price of sugar is increased by 40%. If the
expenditure is not allowed to increase, the ratio between the reduction in consumption and the original consumption is:Solution
Let the price of sugar was Rs. x per kg. After increase in price, new price per kg = x + (x × 40/100) = 7x/5 For Rs. 7x/5 we get 1 kg of sugar. For Re. 1 we get 5/7x kg of sugar. For Rs. x we get 5/7 kg of sugar. Decrease in consumption of sugar = 1 – 5/7 = 3/7 Required ratio = 7/27 : 1 = 7:27
