A rich merchant had collected many gold coins. He did not want anybody to know about him. One
day, his wife asked, " How many gold coins do we have?" After a brief pause, he replied, "Well! if I
divide the coins into two unequal numbers, then 48 times the difference between the two numbers
equals the difference between the squares of the two numbers." The wife looked puzzled. Can you
help the merchant's wife by finding out how many gold coins the merchant has?
