The price of sugar is increased by 5%. By how much percent should a home maker reduce her consumption of sugar to have no extra expenditure? Choose the correct choice from the following options:
A) (700/107) %
B) (107/100) %
C) (500/105)%
D) (5/100)%
E) (100/500)%
Old price = $100 (assume);   Old consumption = 1 kg (assume).   New price = $105.   We want the spendings to remain at $100.   (New consumption)*105 = 100 --&gt; (New consumption) = 100/105 kg.   Percent decrease = Change/Original *100 = (1 - 100/105)/1*100 = 500/105%.   Answer: (500/105)%.
