12The 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 - 1 u
= 6 u
6 u = 36
1 u = 36 ÷ 6 = 6
Number of female passengers at the terminal at first
= 7 u
= 7 x 6
= 42
