Answer 1

- 1 dozen is used to describe a counting of 12 objects.

- 12 contains only two non zero digits and no decimal in it.

- As we know, all the non zero digits are significant, so 12 has only 2 significant figures.

- So,only 2 significant figures are present in the counting of mangoes.

Answer 2

B) 2

Explanation:

In a given number, all non-zero numbers are significant. Also zeros at the right of the number are significant, but not on the left of the number.

So number of significant figures in one dozen mangoes will be number of significant figures in 12.

Number of significant figures in 12 is 1 and 2, so two.

Significant figures = 2

Option B is the answer.
