• A/c to Pigeon principle ,( N+1) is the number of socks must she take out to make sure she has two socks of each color where 'N' is no. of possible types of socks here N=3.
  N+1=3+1---> 4

• Consider blue is first taken then next one is red or yellow. so must taken 1+47+24+1. to ensure second one is also yellow.
