Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

See the condition here State that i=\ i. That means that one element used would go on missing in the next. So leaving one in 1st we get 3 & then in 2nd we use the one left and 2 other and then 3rd only one Will be unique and one Will be left so it's 1 & in last one unique so it's 1. so 3 x 3 x 1 x 1 = 9
