During a class function,
58 of the students were boys and the rest were girls. Halfway, 589 more girls joined in the function and there were
38 as many boys as girls. Find the number of students at the class function in the end.

Boys |
Girls |
Before |
5x3 = 15 u |
3x3 = 9 u |
|
|
+ 589 |
After |
3x5 = 15 u |
8x5 = 40 u |
The number of girls remains unchanged.
LCM of 3 and 5 = 15.
Number of more girls who joined in
= 40 u - 9 u
= 31 u
31 u = 589
1 u = 589 ÷ 31 = 19
Number of students in the end
= 15 u + 40 u
= 55 u
= 55 x 19
= 1045
Answer(s): 1045
