SSC CPO SI and ASI Model Paper 8

(4) Let P be the initial price and Qbe the initial quantity of sugar.
New price after 60% hike in price$=\mathit{P}+60\%\mathit{o}\mathit{f}\mathit{P}=1.6\mathit{P}=\frac{8}{5}\mathit{P}$
In order to have expenditure unchanged,the new quantity has tobe $\frac{5}{8}$Q
Decrease in quantity $=\mathit{Q}-\frac{5}{8}\mathit{Q}=\frac{3}{8}$
Q$\frac{3}{8}\mathit{Q}=9$ kg
⇒ Q = 24 kg
New quantity $=\frac{5}{8}\times 24=15\mathit{k}\mathit{g}$
