How many perfect squares lie between 120 and 300 ?

A. 5

B. 6

C. 7

D. 8

Answer: Option C

Solution(By Examveda Team)

$$\eqalign{ & {\left( {11} \right)^2} = 121{\text{ }} \cr & {\text{And }} \cr & {\left( {17} \right)^2} = 289 \cr} $$
So, the perfect squares between 120 and 300 are the squares of numbers from 11 to 17.
Clearly, these are 7 in number.
