I agree with you.
33-16 = 17girls
24-17 = 7
It may be a typo on the answer sheet.
Of the 60 students in a school, 24 are currently studying chemistry. Exactly 16 of the girls in the school are not currently studying chemistry. The number of girls in the school is 33. How many boys are currently studying chemistry?
Correct answer is 17. How did they get that?
Unclear Explanation: Careful! This is the number of girls in the class. If 16 girls are not studying chemistry, 17 are studying it, leaving 7 spaces in the class for boys.
