          Answer & Explanation
         Answer: D) 700         
         
Explanation: Let number of boys in the school = x
Let number of girls in the school = y
Number of students participated in the sports = 300
Out of which boys = 100 
but given number of boys participated in sports = x/3
=> x/3 = 100
=> x = 300
Remaining girls = 300 - 100 = 200
=> y/2 = 200
=> y = 400
Therefore, total number of students in the school = x + y = 300 + 400 = 700
