उत्तर

x2 + 6y2 = 5xy

Dividing both sides by y2, we get

`x^2/y^2 + (6y^2)/y^2 = (5xy)/(y^2)`

`(x/y)^2 + 6 = 5(x/y)`

`(x/y)^2 - 5(x/y) + 6 = 0`

Let `x/y = a`

∴ a2 – 5a + 6 = 0

`=>` (a – 2)(a – 3) = 0

`=>` a = 2, 3

Hence, `x/y` = 2, 3

A doctor reports blood pressure in millimeters of mercury (mm Hg) as a ratio of systolic blood pressure to diastolic blood pressure (such as 140 over 80). Systolic pressure is measured when the heart beats, and diastolic pressure is measured when it rests. Refer to the table of blood pressure ranges for adults.

Blood Pressure Ranges
  Normal Prehypertension Hypertension
(Very High)
Systolic Under 120 mm Hg 120-139 mm Hg 140 mm Hg and above
Diastolic Under 80 mm Hg 80-89 mm Hg 90 mm Hg and above
