In a classroom, the number of boys and the number of girls are initially equal. 8 girls left to play ring tennis, leaving twice as many boys as girls in the classroom. The total number of girls and boys present initially were ______.
Given:
The number of boys and girls initially were equal
Number of girls left to play ring tennis = 8
Solution:
Let the number of girls left in the classroom after 8 girls left = x
Then number of boys in classroom = 2x
According to question:
x+8 = 2x
2x-x=8
x=8
Hence total number of girls = x+8 = 8+8 =16
And number of boys were equal to girls = 16
Total number of girls and boys = 16+16 =32
