@All.

Yes, it is right that error starts coming with area 195.5 km2, but in that case, only small error is there that is 1 sec, so we neglect it, so we consider greater than 250km2, that would be more so we can't neglect it.

If less than 250 km^2 then plane service consider. More than 250 Km^2 then geodetic service considered, where the curvature of earth surface taken (consider).

According to made easy notes. Show option D is nearest.

Curvature taken into account - more than 250 km^2
Curvature not taken into account - less than 250 km^2

It's 250 km above geodetic survey in 195.5 km error come in the measurement of angles is 1 second.

According to textbooks of agor, khurmi -260km^2.
According to IES Master -195.5km^2.

I think 260 km^2 is the right answer 199.5 area of well condition triangle.

I think 195.5 sq km is correct answer. Can anyone agree with me?

Rups said:   6 years ago
It should be greater than 195.5Km^2. So the answer is 250 right.

MANJU said:   8 years ago
Yes, 195.5 sq km, so the answer is C, 200 sq km the nearest.

Bibhab said:   8 years ago
200km^2 is the correct answer as per the Geodetic survey.
