Answer 2

Answer:

The addition of given numbers is- 

3.52

2.30

+6.24

-----------

12.06

The result cannot have more digits to the right of the decimal point than either of the original numbers.

As 2.3 has the least number of decimal places, i.e. one, therefore sum should be reported to one decimal place only. 

After rounding off, reported sum = 12 which has two significant figures.
