1720The number of female passengers at first and in the end remains unchanged. Make the number of female passengers the same. LCM of 3 and 3 is 3.
Number of male passengers who entered the terminal
= 17 u - 5 u
= 12 u
12 u = 108
1 u = 108 ÷ 12 = 9
Number of male passengers at the terminal at first
= 5 u
= 5 x 9
= 45
Answer(s): 45
