35The number of female passengers at first and in the end remains unchanged. Make the number of female passengers the same. LCM of 1 and 2 is 2.
Number of male passengers who left the terminal
= 14 u - 3 u
= 11 u
11 u = 154
1 u = 154 ÷ 11 = 14
Number of male passengers at the terminal at first
= 14 u
= 14 x 14
= 196
