MPPGCL JE Civil Mock Test - 2 - Civil Engineering (CE) MCQ

40% of 900 + x = 30% of 2600
360 + x = 780
x = 420
Hence, Option C is correct. 

P is male member and married to Q.
P is husband and Q is wife.
R is brother of P.
S is the son of R.
T, who is the sister of S will be daughter of R.
Q is the daughter-in-law of U, whose husband has died means U is the mother of P.

Let X and Y be two buses. Bus X travels the PA, AB, BC, CD.
Now, AD = BC = 25 km.
So, PD = PA +AD = 50km.
Bus Y travels 35km upto E.
Distance between two buses = PQ – (PD + QE)
= [150 – (50 + 35)] = 65 km.

• Shear strength of cohesionless soils is only developed with the presence of effective stress.

• Shear strength increases with increasing effective stress.

• The increase of shear strength of cohesionless soil depends upon the internal friction angles of the soil.

• The type of soil most susceptible to liquefaction is one in which the resistance to deformation is mobilized by friction between particles. If other factors such as grain shape, uniformity coefficient, and relative density are equal, the frictional resistance of cohesion less soil decreases as the grain size of soils becomes smaller.

1. Igneous RocksIt is also known as primary, unstratified, or eruptive rocks. There are formed by volcanic origin and are formed due to the solidification of molten mass lying below or above the earth’s surface. For example, Granite rhyolite, basalt, etc.

2. Sedimentary Rocks

It is also known as aqueous or stratified rocks—the various weathering agencies, rain, sun, air, frost, etc. Break up the surface of the earth. Due to the seasonal variation, sedimentation takes place in layers. With time, the sediments get consolidated in horizontal beds due to the pressure exerted by overlying material, for example, Gypsum, sandstone, limestone, etc.

3. Metamorphic Rocks

Metamorphic rocks are formed from igneous or sedimentary rocks. This type of rock is formed by the action of the earth’s movements, temperature changes, liquid pressures, etc. Ex-Marble, Quartzite, etc.

Hence the correct answer is option C.

Delight is a synonym of Joy. Similarly, Dull is a synonym of Gloomy.

Iso = equal, Gonic = declination, thus isogonic lines represents line obtained from joining points of equal declination.

(c) In 2D incompressible and steady flow, pressure gradient in direction of flow is zero:

Hence the option D is correct.

Hence the option D is correct.

Hence the correct answer is option B.

Hence the correct answer is option C.

Hence the correct answer is option D.

Hence the correct answer is option A.

V₁ = 9.95ml M₁ = 17.5ml

V₂ = 5.60ml M_s = 11.5ml

W_s = 0.4043 = 40.43%

The specific gravity of solids

G = 2.91

Hence the correct answer is option A.

(a)NIL – When there is no perceptible deposit of efflorescence.

(b)SLIGHT- Not more than 10% area of the brick covered with a thin deposit of salt.

(c)MODERATE- Covering up to 50% area of the brick.

(d)HEAVY- Covering 50% or more but unaccompanied by powdering or flaking of the brick surface.

(e)SERIOUS- When there is a heavy deposit of salts accompanied by powdering and/or flacking of the exposed surfaces.

Hence, the correct option is (B)

Hence, the correct option is (B)

A technique for the calculation of slope stability based upon the assumption of a plane

surface of failure through the toe of the slope has been proposed by Culmann. This slope stability analysis method is not widely used since it has been found that plane surfaces of sliding are observed only with very steep slopes, and for relatively flat slopes, the surfaces of sliding are almost always curved.

Hence, the correct option is (C)

Cleaning:

• For cleaning, the top layer of sand is scrapped and 1.5 to 3 cm of sand is removed in each cleaning.

• The frequency of cleaning is 1 to 3 months.

• The rate of filtration is 100-200 l/hr/m2 of filter area.

• It is used for smaller plants in villages.

Rapid sand Filter: They consist of larger sand grains supported by gravel and capture particles throughout the bed. They are cleaned by backwashing water through the bed to 'lift out' the particles.

Cleaning:

1. Cleaning of the filter can also be done using surface wash but it should be accompanied by backwash.

2. Washing period = 24 to 48 hrs.

There are generally six methods of valuation:

i) Rental Method of Valuation

ii) Direct Comparisons of the capital value

iii) Valuation based on the profit

iv) Valuation based on the cost

v) Development method of Valuation

vi) Depreciation method of Valuation

The age of the timbers is determined by “Annual Rings.”

Sapwood →is the outer annual ring between heartwood and cambium layers.

Pith → innermost central portion or core of the tree.
