2x1 = 2 u |
3x1 = 3 u |
12.5% =

1860% =
60100 =
35The number of male passengers at first and in the end remains unchanged. Make the number of male passengers the same. LCM of 1 and 2 is 2.
Number of female passengers who left the terminal
= 14 u - 3 u
= 11 u
11 u = 165
1 u = 165 ÷ 11 = 15
Number of female passengers at the terminal at first
= 14 u
= 14 x 15
= 210
Answer(s): 210
