During a class party,
910 of the students were girls and the rest were boys. Halfway, 238 more boys joined in the party and there were
35 as many girls as boys. Find the number of students at the class party in the end.

Girls |
Boys |
Before |
9x1 = 9 u |
1x1 = 1 u |
|
|
+ 238 |
After |
3x3 = 9 u |
5x3 = 15 u |
The number of boys remains unchanged.
LCM of 3 and 9 = 9.
Number of more boys who joined in
= 15 u - 1 u
= 14 u
14 u = 238
1 u = 238 ÷ 14 = 17
Number of students in the end
= 9 u + 15 u
= 24 u
= 24 x 17
= 408
Answer(s): 408
