MAP = 2/3 DBP + 1/3 SBP
90 = x + 50
x = 40
so DBP = 60

now PP = SBP - DBP
so PP = 150-60 = 90

so pulse pressure = 90

did that make sense? i just winged it.

MAP = 2/3 diastolic + 1/3 systolic

thus 1/3 of systolic 150 is 50 , now MAP - 50 = 40 which is 2/3 diastolic thus diastolic is 60

now pulse pressure is 150 - 60 = 90 ......
