A fruit seller sells mangoes. It's summer and it is also definitely the best and most suited time to enjoy the king of fruits and nature's delight- Mangoes. Anush goes to the mango shop to buy some for home. He asks the mango seller to give him one kilogram of mangoes. The mango seller is a good businessman and thus says that instead of one, he has four different varieties of mangoes. When he is questioned by Anush as to what they are, he is quick to reply - " Neelam , Malgoa, Sendur and Daseri". Anush is left to buy 7 mangoes from these as 7 mangoes make up a kilogram. The fruit seller who is good mathematician too, offers Anush a discount of 50% if he could correctly tell him as to how many different ways are there to purchase this delight. Will you help Anush?
