45The number of male passengers at first and in the end remains unchanged. Make the number of male passengers the same. LCM of 1 and 1 is 1.
Number of female passengers who left the terminal
= 7 u - 4 u
= 3 u
3 u = 24
1 u = 24 ÷ 3 = 8
Number of female passengers at the terminal at first
= 7 u
= 7 x 8
= 56
