The accuracy of measurement also lies in the way the results is expressed. The number of digits to which a value is to be expressed is one digit more than number of digits after after an operation is carried out on the given values. The error can be minimised by many trials and using the correct methods are instruments.
The number of significant figures can reduce in

A

Addition

B

Subtraction

C

Multiplication

D

Division

Text Solution

Verified by Experts

The correct Answer is:
B
To find say difference between `20.17` and `20.15` , we get `0.02` ( i.e ., one significant figure only).
