After |
1x1 = 1 u |
3x1 = 3 u |
12.5% =
1251000 =
1875% =
75100 =
34The number of male passengers at first and in the end remains unchanged. Make the number of male passengers the same. LCM of 1 and 1 is 1.
Number of female passengers who left the terminal
= 7 u - 3 u
= 4 u
4 u = 60
1 u = 60 ÷ 4 = 15
Number of female passengers at the terminal at first
= 7 u
= 7 x 15
= 105
Answer(s): 105
