- A typist uses a paper that measures 32 cm by 20 cm.

- Initially, he leaves a 2 cm margin on all sides. The typing area then is:

- Length: 32 - 4 = 28 cm

- Breadth: 20 - 4 = 16 cm

- Area: 28 * 16 = 448 sq. cm

- If margins are reduced to 1 cm, the new typing area is:

- Length: 32 - 2 = 30 cm

- Breadth: 20 - 2 = 18 cm

- Area: 30 * 18 = 540 sq. cm

- Increase in typing area: 540 - 448 = 92 sq. cm

- Percentage increase: (92 / 448) * 100 = 20.54%

- Correct Answer: Option 1 - 20.54%
