Compared with the prismoidal formula, the end-area (trapezoidal) formula for earthwork volume generally:
सही उत्तर: ग) Tends to overestimate the volume, so a prismoidal correction is subtracted
For typical earthwork solids such as pyramidal frustums, the end-area method gives a larger volume than the prismoidal formula.

With a polar planimeter of multiplying constant M = 100 cm², the initial and final readings are 2.400 and 7.200, the zero mark does not pass the index (N = 0) and the anchor is outside the figure (C = 0). The area is:
सही उत्तर: ख) 480 cm²
A = M (F − I) = 100 × (7.200 − 2.400) = 480 cm².

The point of curvature of a road curve is at chainage 890.80 m, and pegs are to be fixed at every 20 m of through chainage. The length of the first sub-chord is:
सही उत्तर: क) 9.20 m
The next whole 20 m chainage after 890.80 is 900.00, so the first sub-chord = 900.00 − 890.80 = 9.20 m.

Taking the combined curvature and refraction correction as 0.0673 D² (D in km), the maximum distance at which a signal 10 m high can be seen from ground level (ignoring obstructions) is about:
सही उत्तर: घ) 12.2 km
D = √(h/0.0673) = √(10/0.0673) = √148.6 ≈ 12.2 km.

In plane table surveying, the 'traversing' method is used mainly for:
सही उत्तर: ग) Running survey lines along roads, rivers or boundaries, plotting each station from the previous one
Plane table traversing is similar to compass traversing: the table is set at successive stations along a route and oriented by back sighting.

One hectare of land is approximately equal to:
सही उत्तर: ख) 19.66 Ropani
1 hectare = 10,000 m²; 10,000 ÷ 508.74 ≈ 19.66 Ropani.

One Bigha is approximately equal to how many Ropani?
सही उत्तर: क) 13.31
1 Bigha ≈ 6772.63 m² and 1 Ropani ≈ 508.74 m², so 6772.63 ÷ 508.74 ≈ 13.31 Ropani.

One Kattha of land in the Terai of Nepal is equal to:
सही उत्तर: घ) 3645 square feet
1 Bigha = 72,900 sq ft and 1 Kattha = 1/20 Bigha = 3645 sq ft (≈ 338.63 m²).

One Dhur, the smallest unit of the Bigha system used in the Terai of Nepal, is approximately:
सही उत्तर: ग) 16.93 m²
1 Dhur = 182.25 sq ft ≈ 16.93 m² (1 Kattha = 20 Dhur ≈ 338.63 m²).

One Aana, a sixteenth part of a Ropani, is equal to:
सही उत्तर: ख) 342.25 square feet
1 Aana = 5476 ÷ 16 = 342.25 sq ft (18.5 ft × 18.5 ft).
