Solution


Q.

Assertion: Blood pressure of a normal adult is 120/80.
Reason: Blood pressure is measured by sphygmomanometer.
1 Both assertion and reason are correct and reason is the correct explanation of assertion.  
2 Both assertion and reason are correct but reason is not the correct explanation of assertion.  
3 Assertion is true but Reason is false.  
4 Assertion is false but Reason is true  

Ans.

(2)

Sphygmomanometer is the instrument used to measure blood pressure. Whatever be the value it will be obtained after measuring with this. This has no relation with the normal adult blood pressure. Thus, both assertion and reason are correct but reason is not the correct explanation of the assertion.
