1320The number of female passengers at first and in the end remains unchanged. Make the number of female passengers the same. LCM of 5 and 7 is 35.
Number of male passengers who entered the terminal
= 65 u - 21 u
= 44 u
44 u = 396
1 u = 396 ÷ 44 = 9
Number of male passengers at the terminal at first
= 21 u
= 21 x 9
= 189
Answer(s): 189
