Question

A rod of a certain length is divided into 4 pieces of lengths 2.03 m, 6.89 m, 1.7 m and 3.76 m. Which of the following is the length of the rod before the division?

• A. 14.38 m
• B. 14.8 m
• C. 41.83 m
• D. 13.87 m

Answer 1

The correct option is A

14.38 m

Firstly, convert all numbers to like decimals. Therefore the decimal numbers are 2.03, 6.89, 1.70 and 3.76 m.
Now adding the lengths of all the parts, we get:

$2.03$
$+6.89$
$+1.70$
$+3.76$
$\overline{}$
$14.38$
$\overline{}$

Hence the length of the rod before the division was 14.38 m.
