Practice Test: Logical Reasoning - 3 - SSC CGL MCQ

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

Here 2^nd number is twice the number of the square of 1^st number
1) 6 : 72 = 6 × 6 = 36 × 2 = 72
2) 9 : 162 = 9 × 9 = 81 × 2 = 162
3) 12 : 288 = 12 × 12 = 144 × 2 = 288
4) 16 : 476 = 16 × 16 = 256 × 2 = 512 which is not equal to 476
Hence 16 : 476 is the odd number pair

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

Saturday was on 20^th of this month.
Tuesday is three days ahead means today is Saturday.

42 – 6 + 3 × 5 ÷ 8 = 18
42 ÷6*3+5-8=18
Hence option 2 is the correct option.

Here the sum of square root of each number is written in the last column

Hence 17 is the missing number

After arranging them as per the ascending order of dictionary we get;
Mirage, Misogamy, Misogynist, Misology

EYES is used for SIGHT. Similarly, SKIN is used to FEEL.
Hence, “Skin” is the answer.

Anaemia is caused when there is a loss of blood in the body and ​Osteoporosis is 
a disease where increased bone weakness increases the risk of a broken bone.

Similarly, if we rotate direction indicator through 135⁰ in anti-clockwise direction then pointer indicating South would show North – West direction.

In 7584 : 4251;
7 – 3 = 4; 5 – 3 = 2; 8 – 3 = 5; 4 – 3 = 1
Similarly;
4 – 3 = 1; 5 – 3 = 2; 6 – 3 = 3; 3 – 3 = 0Hence, “1230” is correct option.

A + 1 = B; B + 1 = C; C + 1 = D
H + 1 = I; I + 1 = J; J + 1 = K
N + 1 = O; O + 1 = P; P + 1 = Q
Hence the option “DKQ” is correct.

Here the logic is square of every odd number starting from 3
9 = 3 × 3
25 = 5 × 5
49 = 7 × 7
81 = 9 × 9
121 = 11 × 11
169 = 13 × 13
Hence 169 is the missing number.

Table is drawn describing symbols and their meanings:

family chart can be represented as:-

It is clear from the chart that Asha is Dev’s granddaughter.

1. RTWAG = R + 2 = T; T + 3 = W; W + 4 = A; A + 6 = G
2. EGJNR = E + 2 = G; G + 3 = J; J + 4 = N; N + 4 = R
3. NOQUZ = N + 1 = O; O + 2 = Q; Q + 4 = U;U + 5 = Z
4. CEHLQ = C + 2 = E; E + 3 = H; H + 4 = L; L + 5 = Q
Only “CEHLQ” follows the given rule.

Here 1^st and 3^rd number of each row in multiplied and result is written in the middle column.

Hence 35 is the missing number

1. All dresses in that shop are expensive => can be partially true
2. There are cheap dresses also in that shop =>  since most dresses are expensive, not all of them are so.
This means some cheap dresses are also there in the shop.
3. Handloom dresses in that shop are cheap => information is not given about handloom dresses
4. There are no cheap dresses available in that shop => information regarding non availability of cheap dresses is also not given
Hence only option 2 definitely follows the interference.

As ‘RHOMBUS’ is codded as TJQODWU, then, ‘RECTANGLE’ is coded as TGEVCPING. 

Here, “Education” ⇒ “365798214

Therefore “CONDUCT” ⇒ “7146578”

Direction path can be traced as:

⇒ AC = √[(AB)2 + (BC)2]
⇒ AC = √[(12)2 + (5)2]
⇒ AC = √[144 + 25]
⇒ AC = √169
⇒ AC = 13 km
Hence, Shortest distance between Ankit house and School is 13 km.

1) 11, 75, 00, 55, 10 ⇒ R, O, H, A, N
2) 11, 57, 00, 55, 12 ⇒ R, E, H, A, N
3) 32, 67, 41, 55, 12 ⇒ R, O, V, A, N
4) 32, 75, 21, 55, 10 ⇒ R, O, V, A, N
Hence, 11, 75, 00, 55, 10numbers represent “ROHAN”.

“STREET” cannot be formed from “KILOMETERS”as there are only one T in KILOMETERS but street has two T.

The Venn diagram of given statement can be represented as shown below:

 

I. No student is talented. ⇒ False
II. Some girls are not – talented. ⇒ True (as shown in diagram)
Hence, only conclusion II follows

Zebra, Grass eating animal, Lion
1. All Zebras are Grass-eating animals.
2. Not all Grass-eating animals are Zebras.
3. No Grass-easting animal is Lion.
4. No Zebra is Lion.
These 4 points can be represented as:

Hence, diagram in option 2) will complete the pattern
