An amusement park gives an offer to its customers that one person will be given free entry with four other people. What is the effective percentage discount given by the amusement park?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 20%.
Let the entry fee per person = ₹100
Total for 5 people without offer = 5 × 100 = ₹500
But 1 person gets free entry → only 4 pay
Total paid = 4 × 100 = ₹400
Effective discount% = × 100 = 20%
