Solutions

S1. Ans.(d)
Sol. Given, True length of line (L) = 200 m.
True length of Tape (l) = 20 m.
Wrong length of line (L’) = 200.80m.
Actual length of Tape (l’) =?
L × l = L’ × l’
200 × 20 = 200.8 × l’
▭(l^’=19.92 m.)

S2. Ans.(d)
Sol. Annual rent (R) = 20,000
Year purchase (Y.P) = 100/(i%)
= 100/5
▭(Y.P=20)
Capitalized value = Annual rent × Year’s Purchase
= 20,000 × 20
= 400,000 Rs.

S3. Ans.(b)
Sol. Seasoning is the process of adjusting the moisture content of wood or remove the sap from the wood. The moisture content in a well-seasoned timber is about 10-12%
Objective of seasoning →
– Reduce the weight
– Reduction in Shrinkage and warping.
– Increase in strength and durability.
– Remove sap.
– Reduce the tendency of split and decay.

S4. Ans.(b)
Sol. Area of plot =16 km^2
Area of plot in map = 1 cm²
1 cm² = 16 km²
1 cm = 4 km
Representative fraction (R.F.) = 1cm/(4×100000 cm)
▭(R.F.1/400000)

S5. Ans.(a)
Sol. Shear reinforcement in RCC beam is provided to resist diagonal tension. Stirrups is provided in the beam for shear reinforcement. At corner spacing between stirrups decreases and increase towards center.

S6. Ans.(b)
Sol. According to IS :516, concrete cubes are prepared, cured and tested.
