A bicycle tyre should maintain a minimum pressure of 200 kPa. When checked, the pressure of a tyre was found to be only 150 kPa.

A bicycle pump is used to inflate the tyre. One complete stroke of the piston of the bicycle pump forces 175 cm³ of air at atmospheric pressure into the tyre.

The atmospheric pressure is 100 kPa and the volume of the tyre remains fixed at 2000 cm³.

What is the minimum number of strokes required to inflate the tyre pressure to at least 200 kPa?
