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