One fine day, Santa and banta were playing cards, but unexpectedly power went off and they were getting bored. So santa aebitarily inverted position of ten cards out of 52 cards(and shuffled it) and inquired banta to divide card in 2 pile with equal number of inverted cards(number of cards in every pile require not be equal). It was extremely dark in room and banta could not see cards, after thinking bit banta divided cards in 2 piles and quite surprisingly on counting number of inverted cards in both piles were equal. What do you believe banta should have done?
