710The number of female passengers at first and in the end remains unchanged. Make the number of female passengers the same. LCM of 5 and 3 is 15.
Number of male passengers who entered the terminal
= 35 u - 9 u
= 26 u
26 u = 182
1 u = 182 ÷ 26 = 7
Number of male passengers at the terminal at first
= 9 u
= 9 x 7
= 63
Answer(s): 63
