3x3 = 9 u |
1x3 = 3 u |
12 u |

9 u |
1 u |

The number of men at first and in the end remains unchanged. Make the number of men the same. LCM of 3 and 9 is 9.
Number of women who left
= 3 u - 1 u
= 2 u
2 u = 8
1 u = 8 ÷ 2 = 4
Number of people who attended the function
= 9 u + 3 u
= 12 u
= 12 x 4
= 48
Answer(s): 48
