1120The number of male passengers at first and in the end remains unchanged. Make the number of male passengers the same. LCM of 1 and 9 is 9.
Number of female passengers who left the terminal
= 63 u - 11 u
= 52 u
52 u = 676
1 u = 676 ÷ 52 = 13
Number of female passengers at the terminal at first
= 63 u
= 63 x 13
= 819
