This application is practically used especially in making purchase or sale. When a specific quantity is known for a specific amount then for a given amount/quantity you can get the quantity/amount easily.

How it works....?

There are four fields: Quantity_1, Price_1, Quantity_2, Price_2

Quantity_1 and Price_1 are mandatory fields. They must be given values as per known parameter. For Example: if 1 chocolate is for Rs.5, then Quantity_1 would be 1 and Price_1 would be 5.
One of other two fields (Quantity_2, Price_2) must be given to get the result of left field. For Example : If you want to know the price for 10 chocolates then Quantity_2 should be given as 10. Then click Get Result Button to get the amount in Price_2 field.
