12The number of female passengers at first and in the end remains unchanged. Make the number of female passengers the same. LCM of 1 and 1 is 1.
Number of male passengers who left the terminal
= 7 u - 1 u
= 6 u
6 u = 78
1 u = 78 ÷ 6 = 13
Number of male passengers at the terminal at first
= 7 u
= 7 x 13
= 91
Answer(s): 91
