|
Answer» 2) let the petrol consumption before hike be X and petrol price be Y. Total expenditure incurrred by motorist = XYafter hike, the petrol price = Y + 10%ofY =1.1Y let the new consumption be Z according to question, the expenditure needs to remain same.therefore,Z*1.1Y=XY Z = X/1.1=10X/11 Therefore change in consumption = Z-X =-X/11 negative sign means the motorist have to reduce the consumption.Thus, while calculating reduction percentage we will consider magnitude of change.Therefore, percent reduction={(X/11)/(X)}*100% =9.09%Hence, the motorist has to reduce consumption by 9.09% to keep the expenditure same. |
