1320The number of male passengers at first and in the end remains unchanged. Make the number of male passengers the same. LCM of 5 and 7 is 35.
Number of female passengers who entered the terminal
= 65 u - 21 u
= 44 u
44 u = 88
1 u = 88 ÷ 44 = 2
Number of female passengers at the terminal at first
= 21 u
= 21 x 2
= 42
