Question 398066
if the driven mileage before rise is D, then after rise it will be 0.933*D
If the fuel cost before rice is C, then after rise it will be 1.045*C
So the petrol price before rise is {{{p=C/D}}}
the petrol price after rise is {{{P=(1.045C)/(0.933D)=1.12*(C/D)}}}
so percentage the petrol price rise is {{{((P/p)-1)*100%}}}
{{{((1.12*(C/D))/(C/D)-1)*100=12}}}%
