You are provided three scales A, B and C as shown in Fig. to measure a length of 10 cm.

For the correct measurement of the length, you will use the scale,

(a) A only

(b) B only

(c) C only

(d) Any of three scales

Answer 1

For scale A,length of interval available = 15 – 3 = 12 cm
For scale B, length of interval available = 15 – 3 = 12 cm
For scale C, length of interval available = 13 – 0 = 13 cm
So, 10 cm is measurable by all the given scales.
