Q1. Storm-I of duration 5 hours gives a direct run-off of 4 cm and has an average
intensity of 2cm / hr
Storm-II of 8 hour duration gives a run-off of 8.4 cm.
(Assume φ -index is same for both the storms.)
The value of φ − index is
Answer : Option A
Explaination / Solution:
φ - index = (2×5-4)/5 = (10-4)/5 = 6/5 = 1.2 cm/hr
Q2. The local mean time at a place located in longitude 90o 40' E when the standard
time is 6 hours and 30 minutes and the standard meridian is 82o 30' E is
Answer : Option D
Explaination / Solution:
No Explaination.
Q3. A homogeneous gravity retaining wall supporting a cohesionless backfill is shown in the
figure. The lateral active earth pressure at the bottom of the wall is 40 kPa.
The minimum weight of the wall (expressed in kN per m length) required to prevent it
from overturning about its toe (Point P) is
Answer : Option A
Explaination / Solution:
Q4. On a specific highway, the speed-density relationship follows the Greenbegs
model [V = vf loge (kjk)], where vf and kj are the free flew speed and jam density
respectively. When the highway is operating at capacity, the density obtained as
per this model is
Answer : Option D
Explaination / Solution:
No Explaination.
Q5. Group I lists a few devices while Group II provides information about their uses. Match the
devices with their corresponding use.
Answer : Option D
Explaination / Solution:
Aneometer → wind speed
Hygrometer → water vapour content of air
Pilot tube → flow velocity at a specific point in the flow stream
Tensionmeter → Capillary potential of soil water
Q6. A matrix has eigenvalues –1 and –2. The corresponding eigenvectors are 
respectively. The matrix is
respectively. The matrix is
Answer : Option D
Explaination / Solution:
No Explaination.
Q7. For a sample of dry, cohesionless soil with friction angle,Ø the failure plane will be inclined to the major principal plane by an angle equal to
Answer : Option D
Explaination / Solution:
No Explaination.
Q8. Storm-I of duration 5 hours gives a direct run-off of 4 cm and has an average
intensity of 2cm / hr
Storm-II of 8 hour duration gives a run-off of 8.4 cm.
(Assume φ -index is same for both the storms.)
Intensity of storm-II in cm/hr is
Answer : Option D
Explaination / Solution:
Let intensity of storm-II be P cm/hr 1.2 = (P×8-8.4)/8 ⇒ 1.2 × 8 +8.4 = P×8 ⇒ P = 2.25 cm/hr
Q9. A bench mark has been established at the soffit of an ornamental arch at the
known elevation of 100.0 m above mean sea level. The back sight used to establish
height of instrument is a inverted staffreading of 2.105 m. A forward sight reading
with normally held staff of 1.105 m is taken on a recently constructed plinth. The
elevation of the plinth is
Answer : Option D
Explaination / Solution:
No Explaination.
Q10. A three-phase traffic signal at an intersection is designed for flows shown in the
figure below. There are six groups of flows identified by the numbers 1 through 6.
Among these 1, 3, 4 and 6 are through flows and 2 and 5 are right turning. Which
phasing scheme is not feasible ?
Answer : Option C
Explaination / Solution:
No Explaination.
