To measure the length of a pencil by a broken scale, one puts the pencil like this. One end of the pencil reads 4 cm. The other end reads 13.8 cm. The length of the pencil is
A
9.2 cm
B
9.8 cm
C
13.8 cm
D
13.4 cm
Text Solution
Verified by Experts
The correct Answer is:
B
Initial reading = 4 cm Final reading = 13.8 cm So, the length of the pencil = final reading - initial reading = 13.8 cm - 4 cm = 9.8 cm
