While setting a plane table at a station it was found that the error in centering was 30 cm away from the ray of length 40 m drawn from the station. If the scale of the plan is 1 cm = 2 cm, the displacement of the end of the ray in plan from the true position will be

I think the answer should be 0.15 meter not 0.15 centimetre for given data.
30/2 = 15 centimetres.
If the answer is right then the scale of the plan is wrong, it should be 1cm = 2meter.
So answer will be (30/200) = 0.15 centimetres.
30/2 = 15 centimetres.
If the answer is right then the scale of the plan is wrong, it should be 1cm = 2meter.
So answer will be (30/200) = 0.15 centimetres.

@Hemanth.
1cm = 2cm is given Not 2m.
1cm = 2cm is given Not 2m.

60/4000 = 0.015.
Not .15.
Not .15.

It is reduction scale,
The scale should be 1cm = 2 m,
Then (1/200)*30 =0.15 cm.
(Cross multiplication)

Here, 1.5/100=0.015.

1cm=2cm given.
So 30*2= 60cm,
60/4000=0.15.
So 30*2= 60cm,
60/4000=0.15.

1cm=2cm given.
So 30*2= 60cm,
60/40=1.5,
1.5/100=0.15.
So 30*2= 60cm,
60/40=1.5,
1.5/100=0.15.

30 * 2 = 60/4000 = 0.15.
