Solution:
QUESTION: 8

A 30 m metric chain is found to be 0.1 m too short throughout the measurement. If the distance measured is recorded as 300 m, then the actual distance measured will be

Solution:

Actual length of chain = 30 - 0.1 = 29.9 m QUESTION: 9

The length of a chain is measured from

Solution:
QUESTION: 10

A surveyor measured the distance between two points on the plan drawn to a scale of 1 cm = 40 m and the result was 468 m. Later he discovered that he used a scale of 1 cm = 20 m. What is the true distance between the two points?

Solution:

Distance between two points measured with scale of 1 cm to 20 cm
= 468/20 = 23.4 cm
Actual scale of the plan is 1 cm = 40 m
∴ True distance between points
= 23.4 x 40 = 936 m
