Consider the follow lists .

Consider all possible permutations of the letters of the word MASTERBLASTERS

	Column – I		Column – II
i)	The number of permutations containing  the word RAAT is	p)	$\frac{{\left(7!\right)}^2}{3!\times {\left(2!\right)}^4}$
ii)	The number of permutations in which S occurs in first place and R occurs in last place is	q)	$\frac{11!\times 4!}{3!\times {\left(2!\right)}^2}$
iii)	The number of permutations in which none of the letters S,T,R occurs in first 7 positions	r)	$\frac{11!}{3!\times 2!}$
iv)	The number of permutations in which the letters A,S,R occurs in even positions is $\alpha$ then $\frac{\alpha }{7!}$ is	s)	$\frac{12!}{{\left(2!\right)}^4}$
		t)	$\frac{7!}{3!{\left(2!\right)}^4}$
