Should be around 150 psi.
It is: 27 to 44 by dividing them by their hcf which is 15
660 square = 660 x 660 = 435,600
25% of 660= 25% * 660= 0.25 * 660= 165
87% of 660= 87% * 660= 0.87 * 660= 574.2
14% of 660= 14% * 660= 0.14 * 660= 92.4
33% of 660= 33% * 660= 0.33 * 660= 217.8
$660
LCM of 66, 55, 44 = 660
