The price of petrol is increased by 24% a person wants to increase his expenditure by 14%only by what% should he decrease his consumption in order to maintain the same level of expenditure

Question

Answer 1

P+C+PC/100 = E
Acc. to condition,
P=24% and E=14% and we are asked to calculate C which in this case has to be decreased therefore,
24 +(-C) + [24(-C)]/100 = 14
which turns out to be
24 - C - 24*C/100 = 14
on solving C = 8%

Answer 2

P+C+PC/100 = E
Acc. to condition,
P=24% and E=14% and we are asked to calculate C which in this case has to be decreased therefore,
24 +(-C) + [24(-C)]/100 = 14
which turns out to be
24 - C - 24*C/100 = 14
on solving C = 8%
