Hiii 
The formula to find the number of stroke is 
n = [(p*v)- (P*Vi)] / (V*Pa)
where n = number of strokes , 
p = final pressure of air in the tube
v = full capacity volume of tube, 
Vi = Initial volume present in tube
V = Vol. of air delivered by pump in one stroke 
Pa = Atmospheric pressure.
 
after solving this the ans would come as 200 strokes. 
Hope this will help.
