A) 7%
B) \[256\times 1=256.\]
C) \[\frac{1}{n}\]
D) 15%
Correct Answer: C
Solution :
Two successive discounts of x% and y% allowed on an item are equivalent to a single discount of \[\text{Gain }\!\!%\!\!\text{ =}\frac{\text{No}\text{.of articles on CP-No}\text{.of articles on Sp}}{\text{No}\text{.of articles on SP}}\] Hence \[=10,y=5\] \[\frac{S{{P}_{1}}}{100+{{x}_{1}}}=\frac{S{{P}_{2}}}{100+{{x}_{2}}}\]Two successive discount \[\frac{\frac{1}{36}}{100-4}=\frac{S{{P}_{2}}}{100+{{x}_{2}}}\] \[\frac{\frac{1}{36}}{100-4}=\frac{S{{P}_{2}}}{100+8}\]You need to login to perform this action.
