A) 105%
B) 105.3%
C) 110%
D) 115%
Correct Answer: B
Solution :
Given: p = 95% of \[=171\times \frac{100}{95}\times \frac{100}{90}=Rs.200.\] (To find: q) \[\text{Gain }\!\!%\!\!\text{ =}\frac{\text{No}\text{.of articles on CP-No}\text{.of articles on Sp}}{\text{No}\text{.of articles on SP}}\] \[=\frac{25-20}{20}\times 100=25%\] \[\frac{S{{P}_{1}}}{100+{{x}_{1}}}=\frac{S{{P}_{2}}}{100+{{x}_{2}}}\] \[\frac{\frac{1}{36}}{100-4}=\frac{S{{P}_{2}}}{100+{{x}_{2}}}\] To convert into percentage we multiply it by 100, we get \[\frac{\frac{1}{36}}{100-4}=\frac{S{{P}_{2}}}{100+8}\]
