Question : A shopkeeper offers the following three schemes.
Scheme I: Two successive discounts of 15% and 25%
Scheme II: Buy 5, get 3 free
Scheme III: Buy 4, get 6
Which scheme is the best for customers?
Option 1: Scheme I
Option 2: Scheme III
Option 3: Scheme II
Option 4: All are equal
Correct Answer: Scheme II
Solution :
Scheme I: Two successive discounts of 15% and 25%
Final discount = 15 + 25 – $\frac{15\times25}{100}$ = 36.25%
Scheme II: Buy 5, get 3 free
Customers will get a total of 8 items at the price of 5 items.
So, discount = $\frac{3}{8}\times100$ = 37.5%
Scheme III: Buy 4, get 6
Customers will get a total of 6 items at the price of 4 items.
So, discount = $\frac{2}{6}\times100$ = 33.33%
So, scheme II is the best for customers.
Hence, the correct answer is Scheme II.
