1120The number of male passengers at first and in the end remains unchanged. Make the number of male passengers the same. LCM of 3 and 9 is 9.
Number of female passengers who left the terminal
= 15 u - 11 u
= 4 u
4 u = 60
1 u = 60 ÷ 4 = 15
Number of female passengers at the terminal at first
= 15 u
= 15 x 15
= 225
Answer(s): 225
