Q1. Shaquille O’ Neal is a 60% career free throw shooter, meaning that he successfully makes 60 free throws out of 100 attempts on average. What is the probability that he will successfully make exactly 6 free throws in 10 attempts?
Answer : Option A
Explaination / Solution:
Q2. Considering the symmetry of a rigid frame as shown below, the magnitude of the bending
moment (in kNm) at P (preferably using the moment distribution method) is
Answer : Option C
Explaination / Solution:
Axis of symmetry is passing through a column; hence it can be treated as
Q3. Total suspended particulate matter (TSP) concentration in ambient air is to be
measured using a high volume sampler. The filter used for this purpose had an
initial dry weight of 9.787g. The filter was mounted in the sampler and the initial
air flow rate through the filter was set at 1.5min/m3. Sampling continued for
24 hours. The airflow after 24 hours was measured to be 1.4 min/m3. The dry
weight of the filter paper after 24 hour sampling was 10.283g. Assuming a linear
decline in the air flow rate during sampling, what is the 24 hour average TSP
concentration in the ambient air?
Answer : Option C
Explaination / Solution:
No Explaination.
Q4. The flow in a rectangular channel is subcritical. If width of the channel is reduced
at a certain section, the water surface under no-choke condition will

Explaination / Solution:
No Explaination.
Q5. A saturated undisturbed sample from a clay strata has moisture content to
22. % 22 and specific weight of 2.7. Assuming γw = 10 kN/m3, the void ratio and
the saturated unit weight of the clay, respectively are
Answer : Option C
Explaination / Solution:
No Explaination.
Q6. A 3 × 3 matrix P is such that, P3 = P. Then the eigenvalues of P are
Answer : Option D
Explaination / Solution:
Q7. A prismatic beam (as shown below) has plastic moment capacity of Mp, then the collapse
load P of the beam is
Answer : Option C
Explaination / Solution:
Q8. Chlorine gas (8 mg/L as Cl2) was added to a drinking water sample. If the free
chlorine residual and pH was measured to be 2 mg/L (as Cl2) and 7.5, respectively,
what is the concentration of residual OCl- ions in the water? Assume that the
chlorine gas added to the water is completely converted to HOCl and OCl-.
Atomic Weight of Cl: 35.5
Answer : Option B
Explaination / Solution:
No Explaination.

Group I Group II
P. Evapotranspiration 1. Penman method
Q. Infiltration 2. Snyder’s method
R. Synthetic unit hydrography 3. Muskingum method
S. Channel Routing 4. Horton’s method
Answer : Option B
Explaination / Solution:
No Explaination.
Q10.
A saturated undisturbed sample from a clay strata has moisture content to
22. % 22 and specific weight of 2.7. Assuming γw = 10 kN/m3, the void ratio and
the saturated unit weight of the clay, respectively are
Using the properties of the clay layer derived from the above Statement, the
consolidation settlement of the same clay layer under a square footing (neglecting
its self weight) with additional data shown in the figure below (assume the stress
distribution as 1 H : 2 V from the edge of the footing and γw = 10 kN/m3) is
Answer : Option B
Explaination / Solution:
No Explaination.
