Correct Answer: 720


Solution : The total number of students (boys and girls) in schools Y and Z together = 30% + 25% = 55%
The total number of students (boys and girls) in schools X and Y together = 45% + 30% = 75%
Difference = 75% – 55% = 20%
Given: total students = 3600
Thus, 20% of 3600 = $\frac{20}{100}\times3600$ = 720
Hence, the correct answer is 720.
