The price of wheat is decreased by 17.5%. If the expenditure on sugar is to be kept same then the ratio between increase in consumption to actual consumption will be:

7:33

Price × Consumption = Expenditure

*(If expenditure remains same the price is inversely proportional to consumption)

Therefore,

17.5% = \(\frac{7}{40}\)

Price ratio:        40     :     33

Consumption:    33      :     40

Hence,

                        Increase   :     Actual

Consumption:          7        :         33
