Question
The price of sugar is increased by 40%. If the
expenditure on sugar has to be kept the same as earlier, the ratio between the reduction in consumption and the original consumption is:Solution
In the beginning. Let, The rate of sugar = Rs.100/ kg Expenditure = 1 kg. Now, New Rate = Rs.140 per kg Therefore, In Rs.100 sugar bought =100/140 = 5/7kg. Therefore, Reqired ratio =(1 − 5/7) : 1 = 2 : 7
