no of women be A
no of men be B
in city X -> A=B/2-----(1)
in city Y -> A+5=B-10
B-A=15
from 1 B=2A sub in above equation
2A-A=15
A=15 means B=30
in the beginning no of passengers entered the bus is A+B=30+15=45

Let number of women = x. Then, number of men = 2x.
So, in city Y, we have : (2x - 10) = (x + 5) or x - 15.

Therefore Total number of passengers in the beginning = (x + 2x) = 3x = 45
