45The number of female passengers at first and in the end remains unchanged. Make the number of female passengers the same. LCM of 3 and 1 is 3.
Number of male passengers who entered the terminal
= 12 u - 5 u
= 7 u
7 u = 84
1 u = 84 ÷ 7 = 12
Number of male passengers at the terminal at first
= 5 u
= 5 x 12
= 60
Answer(s): 60
