n 2010, the ratio of boys to girls in the top 10 percent of their class at Bixby High School was 3 to 5. In 2011, the number of boys increased by 6 and the number of girls increased by 2. If the new ratio of boys to girls is 2 to 3, write an expression that represents how many students were in the top 10% in 2010.

Answers

Answer:  Total number of students will be 112.

Step-by-step explanation:

Since we have given that

The ratio of boys to girls in the top 10% of their class at Bixby High School was

3:5

So, Let the number of boys be 3x

Let the number of girls be 5x

According to question,

(3x+6)/(5x+2)=(2)/(3)\n\n3(3x+6)=2(5x+2)\n\n9x+18=10x+4\n\n18-4=10x-9x\n\n14=x

So, total number of students will be

3x+5x=8x\n\n8* 14=112

Hence, Total number of students will be 112.
