During a class function,
59 of the students were girls and the rest were boys. Halfway, 52 more boys joined in the function and there were
35 as many girls as boys. Find the number of students at the class function in the end.

Girls |
Boys |
Before |
5x3 = 15 u |
4x3 = 12 u |
|
|
+ 52 |
After |
3x5 = 15 u |
5x5 = 25 u |
The number of boys remains unchanged.
LCM of 3 and 5 = 15.
Number of more boys who joined in
= 25 u - 12 u
= 13 u
13 u = 52
1 u = 52 ÷ 13 = 4
Number of students in the end
= 15 u + 25 u
= 40 u
= 40 x 4
= 160
Answer(s): 160
