DSSSB AE Civil Tier 1 Mock Test - 3 - Civil Engineering (CE) MCQ

Since A, B and C are the angles of a Δ,
∴ A + B + C = 180° .................... (1)
According to question,
A – B = 15° ;
⇒ A = B + 15°...................(2)
B – C = 30°;
⇒ B = C + 30°;....................(3)
Put the value of B from equation (2) in Equation (1), we will get
∴ A = B + 15°
A = C + 30° + 15°
A = C + 45° ......................(4)
From a equation,
∴ A + B + C = 180°
⇒ (C + 45°) + (C + 30°) + C = 180°
⇒ 3C + 45° + 30° = 180°
⇒ 3C = 180° – 75° = 105°
⇒ C = 35° ...........................(5)
From equation (4)
A = C + 45°
Put the value of C from equation (5) , we will get
∴ ∠A = 35° + 45° = 80°.

Base and height of ΔABF and ΔCED are same. Thus their respective areas will be same.

Total area = (Area of △ABF)×2+Area of rectangle BCEF 

Total area = (1/2×10×6)×2+(10×20) = 60+200

Total area = 260cm²

The logic follows here is:-

From The Statement

Parrot is a bird, but 'parrot' is called 'rat'. So 'rat' is a bird.

Hence "rat" is the correct answer.

From the common explanation, we get the position of O is 3rd to the left of M.

Hence, Option B is correct.

i_c = (G + 1) ÷ (1 + e)
= i_c = (2.65 - 1) ÷ (1 + 0.65) = 1

Ion exchange process is used for zero hardness water.
A variety of dissolved solids can be removed by ion exchange. For hardness removal by zeolite (a naturally occurring sodium alumino-silicate material sometime called green sand) and synthetic resins are used.

During sudden closure of valve, a wave of high pressure intensity will be produced in the water, due to this high pressure circumferential and longitudinal stresses will be produced.

In the given set the difference between the consecutive terms is 9 i.e.
Based on same pattern out of given options:
A) (36, 45, 32) ⇒ 36 – 45 = -9 & 45 – 32 = 13
B) (29, 20, 11) ⇒ 29 – 20 = 9 & 20 – 11 = 9
C) (30, 21, 11) ⇒ 30 – 21 = 9 & 21 – 11 = 10
D) (28, 17, 8) ⇒ 28 – 17 = 11 & 17 – 8 = 9
Thus only (29, 20, 11) follows the same pattern as similar to given set.

In gradually varied flow, specific energy (E) is given by the equation:

E = y + v²/(2g)

When dy/dx is positive:

• The depth (y) increases with distance.

For subcritical flow (y > y_c):

• An increase in depth leads to a decrease in velocity.
• This causes the kinetic term to reduce more significantly than the increase in potential energy.

Thus, dE/dx becomes negative when y > y_c.

Area for bearing stress is calculated as A = d × t ; where 'd' is hole diameter of the rivet and 't' is the thickness of the plate where connection is being made.

Rapid Hardening Portland Cement (RHPC) is a special purpose cement used in concrete to achieve a higher rate of early strength development, compared to using Normal Cement. The improved early performance of RHPC is achieved principally through increased product fineness.

Contour interpolation is an operation that first rasterizes contour lines of a segment map with a value domain and then calculates values for pixels that are not covered by segments by means of linear interpolation. Furthermore, on the command line, this operation can also use an input raster map.

Hence, the correct option is (C).
