• A. 3 m
• B. 4 m
• C. 9 m 900 cm
• D. 3 m 400 cm

Answer 1

The correct option is A 3 m

Arun buys 6 m 300 cm of cloth.

$6m300cm=6\times 100+300=6300cm$

He uses 3 m 100 cm of cloth.

$3m100cm=3\times 100+100=3100cm$

$\text{Remaining cloth =}6300-3100=3200cm$

3200 rounded off to 3000 (rounded off to thousands)


3000 cm = 3 m.

Hence, 3 m cloth is left with him.
