Question
The price of sugar is increased by 15%. 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 × 15/100) = 23x/20 For Rs. 23x/20 we get 1 kg of sugar. For Re. 1 we get 20/23x kg of sugar. For Rs. x we get 20/23 kg of sugar. Decrease in consumption of sugar = 1 – 20/23 = 3/23 Required ratio = 3/23 : 1 = 3:23
