Explanation

Total boys = 10+15+25+25+15+15 = 105. Total girls = 30+25+15+10+15+20 = 115. Ratio = 105 : 115 = 21 : 23.

AI explanation

Adding the column values gives the total number of boys as 10 plus 15 plus 25 plus 25 plus 15 plus 15, which equals 105. Adding the corresponding values gives the total number of girls as 30 plus 25 plus 15 plus 10 plus 15 plus 20, which equals 115. The ratio of 105 to 115 simplifies to 21 to 23 by dividing both sides by 5. The result is 21 to 23.
