A shopkeeper gives 2 kite free to a customer on purchase of 30 kites. If he doubles the discount, how many kites should he give free on purchase of 7 kites?
Answer & explanation
Correct answer: option 4
No. of kites free = 2
No. of kites sold = 30 + 2 = 32
Sale = 32 kites (constant)
ATQ, shopkeeper did not increase sale but double the discount only.
It means no. of articles sale will be 32 kites but he gives 4 kites free instead of 2.
Therefore,
on selling 32 kites, free kites = 4
on selling 8 kites, free kites = 1
Hence, on purchase of 7 kites, 1 kite will be free.
