John bought a total of 12 Mangoes and Oranges. Each Mango costs 80 cents and each orange costs 50 cents. If the average price of the 12 mangoes and oranges that John originally purchased was 65 cents, then how many oranges needs to return to raise the average price of his purchase to 72 cents?	Choose the correct choice from the following options: A) 4 B) 5 C) 6 D) 7 E) 8
Let number of mangoes be x, number of oranges be 12-x   0.80x +(12-x)0.50/12 = 0.65   solving for x, we get x = 6 --&gt; Mangoes 6, Oranges 6   Now, number of oranges to be returned be y   [0.80*6 + (6-y)*0.50]/12-y = 0.72   solving for y, y = 4   4ns: 4
