Let x = number of passengers at start.

((x/2)+7)-16 = 17
(x/2)+7 = 33
x/2 = 26
x = 26*2
x = 52

LET X BE THE NUMBER IN THE BUS AT THE BEGINING
HALF GET DOWN =X/2...REMAINING = X/2
7 GET IN ...SO TOTAL =X/2 +7
16 GET OFF AT NEXT STOP.
SO PASSENGERS = X/2 +7 - 16 = X/2 -9 = 17
SO X/2 = 17+9=26
X=52....
