Question 1

A surveyor measured length 60 m drawn on a plan to a scale of 1 cm = 10 m. If was later found that the surveyor used the wrong scale of 1 cm = 15 m for interpretation. What will be the correct length?

Question 2

Which of the following objectives can be achieved by surveying?

i. Preparing archeological maps. Geological maps military maps etc.

ii. Determining Relative position of desired points with respect to a known bench mark.

iii. To measure distance between two points.

iv. Laying Out the alignment of roads, railways etc

Question 3

Planimeter is an instrument used to measure

Question 4

A scale has a representative fraction of  . What will be the length measured on the ground if the length of plan is 5 cm.

Question 5

A plan of an area shrunk such that the line that originally measures 20 cm is now 19.8 cm only. If the original scale was 1cm = 200 m. Consider the following statements:

i. Shrunk scale will be 202.02 m = 1 cm

ii. Correct length corresponding to measured length of 10 m is 10.5 m.

Which of the following statements are correct?
