Question

Taking into account of the significant figures, what is the value of $23.623\text{cm}+8.7\text{cm}$ ?

• A. $32.3$
• B. $32.323$
• C. $32.32$
• D. $32$

Answer 1

The correct option is A $32.3$

When two physical quantities are added or subtracted, there should be as many decimal places retained in the final results as there in the number with the least decimal place. So, $23.623+8.7=32.323=32.3$
