1120The number of female passengers at first and in the end remains unchanged. Make the number of female passengers the same. LCM of 3 and 9 is 9.
Number of male passengers who left the terminal
= 15 u - 11 u
= 4 u
4 u = 40
1 u = 40 ÷ 4 = 10
Number of male passengers at the terminal at first
= 15 u
= 15 x 10
= 150
Answer(s): 150
