Correct Answer: 660


Solution : As per the graph,
The total number of boys in schools A, B, C, D and E = 600 + 450 + 750 + 700 + 800 = 3300
The number of  schools = 5
Average = $\frac{\text{Sum of all the observations}}{{\text{Total number of observations}}}$
The average number of boys in schools = $\frac{3300}{5}$ = 660
Hence, the correct answer is 660.
