Question

A pole is of a certain length, 0.35 m of the pole is painted red, 1.37 m is painted white and 3.27 m is painted black. The remaining 5.63 m is left unpainted. Which of the following is the length of the pole if we round off to the nearest integer?

• A. 10.52 m
• B. 11 m
• C. 12 m
• D. 10 m

Answer 1

The correct option is B

11 m

The total length of the pole is the portion that is painted red, white, black and the portion left unpainted.
The total length of the pole is = 0.35 + 1.37 + 3.27 + 5.63

$0.35$
$+1.37$
$+3.27$
$+5.63$
$\overline{}$
$10.62$
$\overline{}$

The total length of the pole is 10.62 m

Rounding it off to the nearest integer we get the length as 11 m.
