3. The English alphabets are arranged in 3 rows in a Keyboard. Now somebody presses one key in the first row in such a way that there are same number of keys on both sides of that key in that row. Now a second person presses a key in the second row in the same way and a third person also does the same in the third row. Show that it is impossible.

Answer: The patern of keyboard is 10:9:7.the term is when a word selected then there must be same number word beside 2side of row. So though the 2nd and 3rd row agree with this term but 1st don't
