Show Answer
Answer:
Correct Answer: C
Solution:
- Let the CP be Rs. 100. Then, SP = Rs. 120
Let the marked price be Rs. x.
Then, 90% of x =120
$ \Rightarrow $ $ x=\frac{120\times 100}{90}=\frac{400}{3}=133\frac{1}{3}% $
It means he should mark $ ( 133\frac{1}{3}-100 )=33\frac{1}{3}% $ higher than CP.
