In how many ways can 6 rings be worn on the four fingers of one hand..

rings can be worn in ⁵C₄*6! ways i.e. 3600 ways

6c4=6!/4!*2!=5*6/2=15

SOLUTION

Since the no of rings= 6

 "      6 rings can be worn in = 4 fingers

Therefore, now required number of ways = 6c4

                                                         =6!/2!x4!

                                                         =6x5/2

                                                         = 15
