3x3 = 9 u |
37.5% =

75100 =
34The 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
= 9 u - 5 u
= 4 u
4 u = 52
1 u = 52 ÷ 4 = 13
Number of male passengers at the terminal at first
= 5 u
= 5 x 13
= 65
Answer(s): 65
