A shopkeeper gives one kite free to a customer on purchase of 19 kites. If he doubles the discount, how many kites should he give free on purchase of 27 kites?
Answer & explanation
Correct answer: option 2
No. of kites free = 1
No. of kites sold = 19 + 1 = 20
Sale = 20 kites (constant)
ATQ, shopkeeper did not increase sale but double the discount only.
It means no. of articles sale will be 20 kites but he gives 2 kites free instead of 1.
Therefore,
on selling 20 kites, free kites = 2
on selling 10 kites, free kites = 1
on selling 30 kites, free kites = 3
Hence, on purchase of 27 kites, 3 kites will be free.
