7x1 = 7 u |
13x1 = 13 u |
12.5% =

1865% =
65100 =
1320The number of male passengers at first and in the end remains unchanged. Make the number of male passengers the same. LCM of 1 and 7 is 7.
Number of female passengers who left the terminal
= 49 u - 13 u
= 36 u
36 u = 72
1 u = 72 ÷ 36 = 2
Number of female passengers at the terminal at first
= 49 u
= 49 x 2
= 98
Answer(s): 98
