√1919/√0.1919 = A) 0.0001 B) 0.01 C) 100 D) 1000 E) 10,000 Say, x = √1919/√0.1919 = √(1919/0.1919) = √10,000 = 100 Also, x² = (1919/0.1919) = 10,000 = 100 Hence, x = √10,000 = 100 The correct answer is C. Hi Anurag, Just want to expand it little further...suppose one took squared app...

Its quite simple. Let there be n sides of die.
so probability of getting 4 in one throw = 1/n
and probability of not getting 4 in one throw = (n-1)/n
so probability of not getting a 4 i n both the 2 throw = {(n-1)/n}^2
--> {(n-1)/n}^2 = 36/49
--> {(n-1)/n} = 6/7
--> n = 7.
Hence Ans C
