Math in playing cards!

Playing cards

The problem with my friend, Ashish, is that he sees the world in terms of numbers - he tries to find math inside everything!

Now he came to my house on a Sunday armed with a standard deck of playing cards. He wanted me to play cards but I was in no mood for it. So, he chose to test my math skills instead.

He dealt some cards to me and himself from the deck and laid the rest aside. He then said to me, "If you give me certain number of your cards I will have four times as many cards as you have. If I give you the same number of cards, I will have thrice as many cards as you have."

My head had already began to swim, and I developed a terrible headache when Ashish asked me to tell him how many cards each of us had. Please help me determine the number of cards with me and Ashish from the information provided.
