EMRS Junior Secretariat Assistant Mock Test - 4 - EMRS MCQ

1) ADBF = A + 3 = D; D – 2 = B; B + 4 = F
2) BECG = B + 3 = E; E – 2 = C;C + 4 = G
3) DHEI = D + 4 = H; H – 3 = E;E + 4 = I
4) MPNR = M + 3 = P; P - 2 = N; N + 4 = R
Hence, “DHEI” is different from other responses.

R is standing between S and V
⇒ S       R         V
Q is standing to the immediate left of T.
⇒ Q     T
V is standing between R and Q
⇒ R       V         Q
U is fourth left of V and S is immediate right of P
⇒ U P S R V
Combining all three situations we get,
⇒ U P S R V Q T
R is standing at the middle.

option figure 4) completes the question figure as:

Numbers of rectangle are shaded below:-

Hence the number of rectangles are 10.

Here the ‘arrow’ is at the top of the real image. So, it will come at the bottom of the mirror image. And the ‘question’ mark is at the bottom of the real image. So, it will come at the top of the mirror image. Since the mirror is places on the MN line, the ‘exclamation’ mark will remain in the left but its orientation will be opposite. Similar is the case of ‘comma’.

Pituitary, Pineal and Thyroid are glands whereas Thalamus is a part of a Brain and not a gland.

Here in every option number of triangles and cross signs are same except in option 4 where number of triangles is less than number of cross sign.
Hence option 4 is correct option

We know that,
Where, A = Final amount, P = Principal amount, R = % rate of interest, T = time period in years
Here, P = Rs. 1600, T = 2 years, A = 1730.56

Thus, rate of R% per annum is 4%

Speed = distance/time
Let the distance be x km. Then,
(Time taken to walk x km) + (Time taken to ride x km) = 37 min.
⇒ (Time taken to walk 2x km) + (Time taken to ride 2x km) = 74 min.
Given, time taken to walk 2x km = 55 min.
Time taken to ride 2x km = (74 - 55) min = 19 min

We know that,
Property- If MNO is a secant to a circle intersecting the circle at M and N and OT is a tangent segment, then
OM × ON = OT²
From the diagram,
PAB is a secant to a circle with center O₁ intersecting the circle at A and B and PT is a tangent segment,
∴ PA × PB = PT²  ……. (1)
Again, PAB is a secant to a circle with center O₂ intersecting the circle at A and B and PQ is a tangent segment,
∴ PA × PB = PQ²  ……. (2)
From (1) and (2)
PT² = PQ²
⇒ PT = PQ

As we know, in an equilateral triangle all sides are equal.
∴ XY = YZ = ZX
Let XY = 2a units
∴ YZ = ZX = 2a units
And XS is perpendicular bisector of side YZ
∴ YS = SZ = a units
Thus, XY: YS = 2: 1

As stated in above figure ABCD is a cyclic trapezium with Line AD and Line BC parallel to each other.
As per the properties of cyclic quadrilateral,
∠ABC + ∠ADC = 180°
72°+ ∠ADC = 180°
∠ADC = 108°
Also, Properties of parallel lines
∠ADC + ∠BCD = 180°
∠BCD = 180° - ∠ADC = 180° - 108° = 72°
∴ ∠ABC = ∠BCD
⇒ ∠BCD= 72°

From given data
Radius of the wheel r = 3/2 = 1.5 m
⇒ Circumference of the wheel = 2πr = 2π × 1. 5 = 3π = 9. 42 m
Given that wheel makes 8 revolutions per second
⇒ Distance travelled in 1 second = 8 × 9.42 = 75.36 m
⇒ Distance travelled in one hour = 75.36 × 3600 = 271296 m = 271.296 km
∴ Speed of the train ≈ 271.30 km/hr

From given data
Let the cost price of the article be Rs. 100, then marked price = Rs. 135
Selling price = 135 – 31/5% of 135 = 135 – 8.37 = 126.63
∴ Profit percent = (126.63 – 100)/100 × 100 = 26.63 %

Silicosis is a form of occupational lung disease caused by inhalation of crystalline silica dust. The other two diseases are caused by lack of nutrition in the body.

Bronze is an alloy of Copper (Cu)and Tin (Sn).

The Higgs boson is an elementary particle in the Standard Model of particle physics. The question of the Higgs field's existence has been called by some, "the central problem in particle physics".

Gynoecium is most commonly used as a collective term for the parts of aflower that produce ovules and ultimately develop into the fruit and seeds.

Black soil which is extremely fertile for the growth of cotton is found in the states of Maharashtra, Madhya Pradesh, parts of Karnataka, Andhra Pradesh, Gujarat and Tamil Nadu, located in the Deccan plateau. Hence, it is not found in the state of West Bengal.

'A' is an article which is used to refer to something indefinite. 'An' works on the same grounds, but only for nouns/pronouns beginning with a vowel. Something that has already been referred to, indicating that it is definite or specific, would have 'the' as the preceding article. Since the question clearly states that the pond is being referred to for the first time and the succeeding word does not begin with a vowel, 'an' and 'the' may be ruled out. Therefore, 'a' is the correct answer to this question.

Commissioned means come to starts and terminated means comes to end. Commission means mission or we can also called as a special group delegated to consider some matter. Termination means a coming to end of a contract period. The antonym for the commission is probit.
