34The number of female passengers at first and in the end remains unchanged. Make the number of female passengers the same. LCM of 5 and 1 is 5.
Number of male passengers who entered the terminal
= 15 u - 3 u
= 12 u
12 u = 180
1 u = 180 ÷ 12 = 15
Number of male passengers at the terminal at first
= 3 u
= 3 x 15
= 45
Answer(s): 45
