710The number of male passengers at first and in the end remains unchanged. Make the number of male passengers the same. LCM of 1 and 3 is 3.
Number of female passengers who left the terminal
= 21 u - 7 u
= 14 u
14 u = 182
1 u = 182 ÷ 14 = 13
Number of female passengers at the terminal at first
= 21 u
= 21 x 13
= 273
