(c) 2.5d
(d) 3.0d
Q6. The ratio between adopted centrifugal ratios for roads and railways is
(a) 3 : 1
(b) 2 : 1
(c) 5 : 1

Solutions
S1. Ans.(a)
Sol. Arrangement of scale from largest to smallest.
▭(1∶500>1:1000>1∶2500>1∶50,000)
Hence, 1∶500 is the largest scale.
S2. Ans.(a)
Sol. The strength of cement decreases after storage.
Time | Reduction in strength |
3 months
6 months 1 year 2 years |
10%
20% 40% 50% |
S3. Ans.(d)
Sol. The correct relationship between TOD, COD and BOD is
▭(TOD>COD>BOD)
S4. Ans.(c)
Sol. Correct sequence of the parts of a canal system is
Head works → main canal → Branch canal → Distributary → Minor.
S5. Ans.(c)
Sol. Minimum pitch of rivets should be 2.5 times the nominal diameter or rivet i.e. 2.5d.
d = nominal diameter of rivet.
S6. Ans.(b)
Sol.
→ Maximum value of centrifugal ratio for roads = 1/4
→ Maximum value of centrifugal ratio for railways = 1/8
So, ratio between these two = (1/4)/(1/8)
= (2 : 1)
