• let petrol x rs/lit
  taking initially we hv 100/-
  so petrol gets 100/x
  nw new price is 5x/4
  so petrol 115*4/5x=92/x
  so 8% he will reduce

• let in rs x we are getting y petrol
  in increase of 25 % the same y petrol would be now at rs (5x/4) {25% of x +x}
  but he can only increase his expenditure upto (115x/100) {15%x + x}
  so he will get onle (115 y/125 ) in (115x/100) so the ans
  so the reduction in petrol is 10y/125
  dat is 8%

• suppose 1 liter of petrol is 100rs and assume he spends 200rs on petrol
  so no lit he obt is 2lit(200/100) now increase on petrol is 25% and Amount he spends is 15% then i lit of petrol is 125 and amnt spended is 230
  no of lit now he obt is 1.84
  percentage dec is (2-1.84/2)*100=8%
