#combinotirics
Find the largest integer value of x such that the following inequality holds: (10 C x-1) <2*(10 C x) In this question if solved line by line i am getting x<6. but clearly if you put x=7, it satisfies the inequality and 7 becomes the largest integer. Is there a procedure to get answer 7 step by step??
