How many perfect squares lie between 120 and 300?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 7
We look for perfect squares between 120 and 300.
- $11^2 = 121$
- $12^2 = 144$
- $13^2 = 169$
- $14^2 = 196$
- $15^2 = 225$
- $16^2 = 256$
- $17^2 = 289$
- $18^2 = 324$ (exceeds 300)
So the perfect squares are:
121, 144, 169, 196, 225, 256, 289
Total number of perfect squares = 7
