During a class celebration,
59 of the students were boys and the rest were girls. Halfway, 116 more girls joined in the celebration and there were
49 as many boys as girls. Find the number of students at the class celebration in the end.

| Before |
5x4 =
20 u |
4x4 =
16 u |
| |
|
+ 116 |
| After |
4x5 =
20 u |
9x5 =
45 u |
The number of girls remains unchanged.
LCM of 4 and 5 = 20.
Number of more girls who joined in
= 45 u - 16 u
= 29 u
29 u = 116
1 u = 116 ÷ 29 = 4
Number of students in the end
= 20 u + 45 u
= 65 u
= 65 x 4
= 260
Answer(s): 260
