35The number of female passengers at first and in the end remains unchanged. Make the number of female passengers the same. LCM of 5 and 2 is 10.
Number of male passengers who entered the terminal
= 15 u - 6 u
= 9 u
9 u = 90
1 u = 90 ÷ 9 = 10
Number of male passengers at the terminal at first
= 6 u
= 6 x 10
= 60
Answer(s): 60
