Question

While measuring the length of a pencil, the reading of the scale at one end is 25 cm and at the other end is 35.5 cm. Find the exact length of the pencil using these readings.

• A. 35.5 cm
• B. 1.5 cm
• C. 10.5 cm
• D. 105 cm

Answer 1

The correct option is C 10.5 cm

Given,
One end is at 25 cm
Another end is at 35.5 cm
Length of the pencil = Difference between the two readings on the scale
= 35.5 cm - 25 cm
= 10.5 cm
Thus, the length of the pencil is 10.5 cm.
