Q1. The bearings of two inaccessible stations, S1 (Easting 500 m, Northing 500 m) and S2 (Easting
600 m, Northing 450 m) from a station S3 were observed as 225° and 153° 26′ respectively. The
independent Easting (in m) of station S3 is:
Answer : Option C
Explaination / Solution:
Q2. The dominating microorganisms in an activated sludge process reactor are
Answer : Option A

Q3. A road is being designed for a speed of 110 km/hr on a horizontal curve with a super
elevation of 8%. If the coefficient of side friction is 0.10, the minimum radius of the curve (in
m) required for safe vehicular movement is
Answer : Option D
Explaination / Solution:
Ruling gradient = V2/(127(e+f))
= (110×110)/(127(0.08+0.10)) = 529.30m
