Question

Blood : Sphygmomanometer :: Air:
​

Answer 1

Answer:

The relation will be - Blood : Sphygmomanometer :: Air : Barometer

The relationship between the first two terms is, sphygmomanometer is an instrument which is used to measure the pressure of blood.

Now, for the fourth term we have to write the name of such an instrument which is used to measure the pressure of air (third term here).

And, the instrument which is used to measure air pressure is barometer.

So, w.r.t pressure measurement relation, the fourth term will be 'barometer'.

• Blood → First term

• Instrument to measure blood pressure → Sphygmomanometer → Second term

• Air → Third term

• Instrument to measure air pressure → Barometer → Fourth term
