A grocery store bought some mangoes at a rate of 4 for a dollar. They were separated into two stacks, one of which was sold at a rate of 3 for a dollar and the other at a rate of 6 for a dollar. What was the ratio of the number of mangoes in the two stacks if the store broke even after having sold all of its mangoes?	Options
A) 1:4  B) 1:5  C) 2:3  D) 1:2  E) 1:2
The cost price of a mango = 1/4 dollars.   The selling price of a mango from the first stack = 1/3 dollars --&gt; the profit from one mango = 1/3 - 1/4 = 1/12 dollars.   The selling price of a mango from the second stack = 1/6 dollars --&gt; the loss from one mango = 1/3 - 1/6 = 1/6 dollars.   The profit from one mango from the first stack is 4 times the loss from one mango from the second stack.   the ratio is 1/12*6/1 = 1/2 =1:2   1:2
