Options:
- a) 20%
- b) 25%
- c) 30%
- d) 16.67%
- a) 20%
- b) 25%
- c) 30%
- d) 16.67%
correct answer : b)
Explanation:
Let CP per article = 1. CP of 20 = 20. SP of 16 = 20 → SP per article = 20/16 = 5/4. Profit% = (SP−CP)/CP×100 = (5/4−1)/1×100 = (1/4)×100 = 25%.
माना प्रति वस्तु CP = 1। 20 का CP = 20। 16 का SP = 20 → प्रति वस्तु SP = 5/4। लाभ% = (5/4−1)×100 = 25%।
