1320The number of male passengers at first and in the end remains unchanged. Make the number of male passengers the same. LCM of 7 and 7 is 7.
Number of female passengers who entered the terminal
= 13 u - 1 u
= 12 u
12 u = 60
1 u = 60 ÷ 12 = 5
Number of female passengers at the terminal at first
= 1 u
= 1 x 5
= 5
