Total	0.034 g

• A. 0.012 g
• B. 0.0012 g
• C. 0.12 g
• D. 1.2 g

Answer 1

The correct option is A 0.012 g

Weight of pen = 0.02 g
Weight of rubber = 0.002 g
Total weight = 0.034 g

Weight of pen + Weight of rubber
= 0.02 g + 0.002 g
= 0.022 g

Weight of Pencil
= Total weight - (Weight of pen + Weight of rubber )
= 0.034 g - 0.022 g
= 0.012 g
