Practice Test: Logical Reasoning - 1 - SSC CGL MCQ

A bird’s mode of transport is through the air. The man-made creation that serves a similar purpose is the aeroplane.
Similarly, a fish’s medium of transport is through water. The corresponding man-made mode of transport is a boat.

The first phrase consists of letters written in reverse alphabetical order (D → C → B → A). The corresponding phrase is in regular alphabetical order (W → X → Y → Z).
Similarly, the given phrase is in regular alphabetical order (I → J → K → L). Therefore, the required word must be in reverse alphabetical order.
Further, the last letter of the first phrase (A) is the first letter of the alphabet, and the last of the second word (Z) is the first in reverse alphabetical order.

L is the 12th in regular order, and therefore the last letter of the required word must end with the same position in reverse order, i.e. O.
Therefore, the required word is RQPO.

The difference between the first pair is 221, i.e. 381 – 160 = 221.
Therefore, the required answer will be 478 – 221 = 257.

Affluent, Rich and Well-to-do all refer to high level of material wealth. However, prestigious refers more to stature or achievements than material wealth.

By rearranging the letters such that the second and first place are interchanged, the letters should be every alternate letter in the alphabet.
1) OMQ → MOQ → M N O P Q
2) TPR → PTR → P Q R S T → Does not satisfy.
3) TRV → RTV → R S T U V
4) VTX → TVX → T U V W X
Therefore, TPR is the odd answer.

There is a difference of three between each pair.
11 – 8 = 3, 4 – 1 = 3, 10 – 7 = 3.
However, 5 – 3 = 2, and therefore this is the odd one out

Words in dictionary order are listed such that they are in alphabetical order on the basis of the first letter they differ in. Therefore, the order will be :
Latent (4), Latitude (5), Lattice (3), Laugh (2), Launch (1).

The relation between the letters is as follows,
X – 3 = U, U – 3 = R, R – 3 = O, O – 3 = L
F + 1 = G, G + 2 = I, I + 3 = L, L + 4 = P
B + 2 = D, D + 3 = G, G + 4 = K, K + 5 = P
Hence the next term is LPP.

The difference between each increases by one.
2 – 1 = 1
4 – 2 = 2
7 – 4 = 3
Therefore, the required number will be 7 + 4 = 11, or 16 – 5 = 11.

therefore, since X and Y are brothers, and X and A are brothers, Y and A are brothers. This makes Y the brother in law of B.

1) A is shorter than B but taller than C.
⇒ C < A < B
2) D is shorter than A but taller than C.
⇒ C < D < A < B
3) E is shorter than B but taller than A.
⇒ C < D < A < E < B
Therefore, C is the shortest.

Let us consider each option.
1) DISSERTATION → SISTER
2) DISSERTATION → STATION
3) DISSERTATION → DIRECTION
4) DISSERTATION → RATION.
There is no ‘C’ in dissertation, and therefore, direction cannot be formed.

Each letter is denoted by its corresponding numeric place in the alphabet.

Therefore, H = 8, E = 5, A = 1 and R = 18.
On adding these, we get 8 + 5 + 1 + 18 = 32.

By putting in the required operators into the system, we get :
18 × 36 / 12 – 6 + 7
On applying BODMAS, we get
18 x (36/12) – 6 + 7
= (18 x 3) – 6 + 7
= 54 + 1
= 55

Here the logic is as follows,
9 × 8 = 72, 3 × 9 = 27, 2 × 7 = 14
⇒ 72 – 27 – 14 = 31
8 × 7 = 56, 3 × 8 = 24, 3 × 4 = 12
⇒ 56 – 24 – 12 = 20
Similarly,
7 × 9 = 63, 2 × 5 = 10, 1 × 2 = 2
⇒ 63 – 10 – 2 = 51
Hence the required number is 51.

Here the relation is as follows : column 1 × √column 3 = column 2
Thus,
7 × √4 = 7 × 2 = 14
4 × √9 = 4 × 3 = 12
Similarly,
6 × √x = 24
√x = 24/6
x = 4²
x = 16
Hence the required number is 16.

Since Rahul has walked 30 meters to the right, and later 30 meters to the left, he is back in the same line which he originally started in.
Therefore, the total distance from the initial point will be given by the distance he covered towards the south, i.e. 30 + 20 = 50 meters.

each statement after analyzing the least possible Venn diagram.

Conclusions:
I. All teachers are women → It’s possible but not definite, hence false.
II. Some women are teachers → It’s possible but not definite, hence false.
III. Some women are actors → It’s definite, hence true.
IV. All actors are teachers → It’s possible but not definite, hence false.
Therefore, only conclusion III will follow.

Let us check the number of triangles formed,

Hence 28 triangles are formed.

As we all know Pencil comes under Stationery items whereas Potatoes is an edible item.

So the correct Venn diagram is as follows,

The required image should have circle in middle with a diameter from north - east to south - west. There should be a slanting line at upper left corner and a ‘T’ at lower right corner.

Hence the required image is as shown,

The image given in question is hidden in the following image as shown,

When we open the paper step by step, we get the following figure.

The mirror image of the given figure is as shown,

Let’s check each option,
1) 34, 43, 40, 56 → LEAD
2) 10, 31, 77, 99 → LEND
3) 41, 12, 41, 59 → LELF
4) 22, 14, 65, 75 → LAND
Hence the correct representation of the word LEND is 10, 31, 77, 99.
