How many non-perfect squares lie in between 752 and 762 ?
Options:
A . 75
B . 100
C . 125
D . 150
Answer: Option D : D Between the squares of any two consecutive numbers n and (n+1), lie 2n non-perfect squares. Therefore between squares of 75 and 76 (n = 75 and n + 1 = 76), lie (2 x 75) = 150 non-perfect squares.
