-
If a chain is longer than its standard length, the measured distance will be:
सही उत्तर: क) Less than the true distance, so the correction is positive
A too-long chain fits fewer times, so measured length is too small; true length = measured × (L'/L).

The tallies on a 20 m metric chain are placed at every:
सही उत्तर: घ) 5 m
Brass tallies are fixed at every 5 m on a metric chain, with small rings at every metre.

Gunter's chain is 66 feet long and is divided into how many links?
सही उत्तर: घ) 100
Gunter's chain has 100 links, each 0.66 ft (7.92 in); 10 square chains make an acre.

The length of a metric chain commonly used in surveying is:
सही उत्तर: ग) 20 m or 30 m
Metric chains are 20 m or 30 m long; the 66 ft Gunter's chain and 100 ft Engineer's chain are older units.

Geodetic surveying differs from plane surveying because it:
सही उत्तर: ग) Takes the curvature of the earth into account
Geodetic surveys cover large areas and account for the spheroidal shape of the earth.

-
A survey in which the curvature of the earth is neglected is called:
सही उत्तर: ग) Plane surveying
Plane surveying treats the earth's surface as flat and is suitable for small areas (up to about 250 km²).

Ranging rods are painted in alternate bands of red and white (or black and white), each band usually being:
सही उत्तर: ख) 20 cm long
Ranging rods (2 or 3 m long) are painted in 20 cm bands so they are visible and can roughly measure short lengths.

The amount of cement required for 1 m³ of 1:4 cement-sand mortar, taking dry volume factor 1.30 and cement density 1440 kg/m³, is about:
सही उत्तर: घ) 374 kg
Cement volume = 1.30 × 1/5 = 0.26 m³; mass = 0.26 × 1440 ≈ 374 kg (about 7.5 bags).

-
To prepare 1 m³ of wet cement mortar, the dry volume of materials taken is usually increased by about:
सही उत्तर: घ) 27% to 33%
Dry volume is taken about 1.27–1.33 times the wet volume to account for voids filled when water is added.

For ordinary brick masonry, a commonly used cement-sand mortar ratio is:
सही उत्तर: क) 1 : 6
1:6 cement-sand mortar is common for general brickwork; richer mixes like 1:4 are used for load-bearing or exposed work.
