Solutions

S1. Ans.(d)
Sol. Cambium layer → It is a thin layer of fresh sap lying between sap wood and inner bark. It decides the future growth of the tree.

S2. Ans.(a)
Sol. 1 feet = 12 inch
3 feet = 12 × 3 = 36 inches
3 feet = 36 × 2.54 [∵ 1 inch = 2.54cm]
3 feet = 91.44 cm.
3 feet = 0.9144m.
▭(3 feet=1 yard) [∵1 yard=0.9144 m.]

S3. Ans.(c)
Sol. Dosage of Coagulant depends upon the turbidity and colour of water which is determined using JAR TEST.

S4. Ans.(c)
Sol. Given, W = 8t
L = 15 m
Maximum bending moment (M_max )=wl/4
=(8×15)/4
▭(M_max=30 t.m)

S5. Ans.(c)
Sol. As per IRC: –
(1) The width of road for single lane NH or SH in plain and rolling terrain is 12m.
(2) The width of road for single lane NH or SH in mountainous or steep terrain is 6.25 m.

S6. Ans.(c)
Sol. Valuation → It is the technique of find the fair price of an existing building or property or machine.
Purpose of valuation
→ Rent fixation
→ Taxation
→ Mortgage
→ Expenditure
→ Material used
Gross income is not the purpose of valuation
