Question

Two numbers are in the ratio 5: 7. Their difference is 10. Find the numbers.

Sum

Solution

Ratio between two numbers = 5:7

Difference = 7-5 = 2

If difference is 2, then first number = 5

and if difference is 10, then first number

`= 5/2 xx 10 = 25`

and second number = `7/2 xx 10 = 35`

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

Manohar is a healthy 37 years old man whose blood pressure is in the normal category.
