Question

if end of ruler is broken than starts reading from 1.2cm .the final reading of a pencil is 7.6 cm. what will be the actual reading of the pencil​

Answer 1

Answer:

Reading of the pencil started from 1.2 is equal to 7.6

actually we must start from 0 to get correct reading.

but it is 1.2 more than 0.

So, to get actual reading we should subtract 1.2 from 7.6

=>7.6-1.2=6.4

6.4 is the correct reading.
