Given: 6 boxes B1, B2, B3, B4, B5 and B6 are kept one above the other but not necessarily in the same order.

  1. B4 is kept at second place from top.

2) Only two boxes are kept below B1.

  1. Only B5 is kept below B2.

4)  B6 is kept above B3.

B6

If 15 A 35 B 40 C 50 = 60 and 20 A 18 B 24 C 28 = 42, then 70 A 18 B 35 C 48 = ?

  1. ((a))

  2. ((b))

    115

  3. ((c))

    101

  4. ((d))

    110

Show Answer
Answer: ((c))

101

The logic followed here is:

Logic: ( a + b) − c + d

Now, 15 A 35 B 40 C 50 = 60

(15+35)−40+50=50−40+50=10+50=60

For, 20 A 18 B 24 C 28 = 42

(20+18)−24+28=38−24+28=14+28=42

Similarly, For 70 A 18 B 35 C 48 = ?

(70+18)−35+48 = 101

Thus,  70 A 18 B 35 C 48 = 101

Hence, the correct answer is 'Option 3'.

In the following question below are given some statements followed by some conclusions based on those statements. Taking the given statements to be true even if they seem to be at variance from commonly known facts. Read all the conclusions and then decide which of the given conclusion logically follows the given statements.

Statements:

I. Some land are hard.

II. No stone is hard.

Conclusion:

I. All stone are land.

II. Some hard are land.

  1. ((a))

    Both conclusions I and II follows

  2. ((b))

    Only conclusion II follows

  3. ((c))

    Neither conclusion follows

  4. ((d))

    Only conclusion I follows 

Show Answer
Answer: ((b))

Only conclusion II follows

Given Statements:

I. Some land are hard.

II. No stone is hard.

The least possible Venn diagram for the given statement is:

Conclusions:

I. All stone are land:

The statements define the relationship between Land and Hard, and Stone and Hard.

They give no information about the direct relationship between Stone and Land.

Conclusion I does not follow.

II. Some hard are land:

This conclusion is an immediate and definite inference (conversion) from Statement I (Some land are hard).

The statement "Some A are B" can always be converted to "Some B are A."

Conclusion II follows.

So, Only conclusion II follows.

Hence, the correct answer is "Option 2".

In a certain code language, ‘KMENY’ is written as ‘17’, ‘YTAMU’ is written as ‘20’. What is the code for ‘NSDJQ’ in that code language?

  1. ((a))

    20

  2. ((b))

    16

  3. ((c))

    18

  4. ((d))

    17

Show Answer
Answer: ((b))

16

The logic followed here is:

Logic: Code = (Sum of letter positions) ÷ 4

For, ‘KMENY’ is written as ‘17’

Letters: K(11) + M(13) + E(5) + N(14) + Y(25)

Sum = 11 + 13 + 5 + 14 + 25 = 68

68 ÷ 4 = 17

For, ‘YTAMU’ is written as ‘20’’

Y(25) + T(20) + A(1) + M(13) + U(21)

Sum = 25 + 20 + 1 + 13 + 21 = 80

80 ÷ 4 = 20

Similarly, For NSDJQ

N(14) + S(19) + D(4) + J(10) + Q(17)

Sum = 14 + 19 + 4 + 10 + 17 = 64

64 ÷ 4 = 16

So, NSDJQ coded as 16 in the given language.

Hence, the correct answer is "Option 2".

    XYZ

  3. ((c))

    ZMR

  4. ((d))

    RNQ

Show Answer
Answer: ((a))

LYX

The logic followed here is:

So, LYX will replace the question mark in the given series.

Hence, the correct answer is "Option 1".

    G

Show Answer
Answer: ((c))

E

Given: Eight girls A, B, C, D, E, F, G and H are sitting around a circular table facing towards the centre (not necessarily in the same order).

  1. A is second to the left of D.

  2. D is third to the left of E.

  3. C is third to the right of G.

  4. G is not the immediate neighbour of E.

5) H is third to the right of B.

6) B is second to the right of G.

Thus, E is sitting on the immediate right of C.

Hence, the correct answer is "Option 3".

If 51 * 16 @ 18 # 25 = 24 and 58 * 20 @ 24 # 46 = 8, then 45 * 55 @ 10 # 20 = ?

  1. ((a))

    80

  2. ((b))

    75

  3. ((c))

    70

  4. ((d))

    90

Show Answer
Answer: ((c))

70

The logic followed here is:

Now, 51 * 16 @ 18 # 25 = 24

(51+16)−(18+25)

→ 67−43= 24

For,  58 * 20 @ 24 # 46 = 8

(58+20)−(24+46)

→ 78 − 70 = 8

Similarly, For  45 * 55 @ 10 # 20 = ?

(45+55)−(10+20)

→ 100 − 30 = 70

Thus,  45 * 55 @ 10 # 20 = 70

Hence, the correct answer is 'Option 3'.

    -25

  3. ((c))

    0

  4. ((d))

    5

Show Answer
Answer: ((a))

-24

The logic followed here is:

thus, "-24" will replace the question mark in the given series.

Hence, the correct option is "Option 1".

Show Answer
Answer: ((b))

Technology

The correct order of words as they would appear in the English dictionary is:

4. Technic 1. Technical 5. Technician 3. Technique 2. Technology

Thus, the fifth word in the dictionary order is Technology.

Hence, the correct answer is "Option (2)".

    85

  3. ((c))

    183

  4. ((d))

    100

Show Answer
Answer: ((a))

164

The logic followed here is:

Logic: E: '+' , F: '+', G: '×'

Now, For 10 E 12 F 8 G 18 = 166 

→ 8×18 = 144

→ 12 + 144 = 156

→ 10 + 156 = 166

For, 154 E 50 F 20 G 15 = 504

→ 20×15 = 300

→ 50 + 300 = 350

→ 154 + 350 = 504

Similarly, For  25 E 7 F 12 G 11 = ?

→ 12 × 11 = 132

→ 7 + 132 = 139

→ 25 + 139 = 164

Thus, 25 E 7 F 12 G 11 = 164

Hence, the correct answer is 'Option 1'.

  4. ((d))

    Only conclusion I follows

Show Answer
Answer: ((a))

Both conclusions I and II follows 

Given Statements:

I. No J is M.

II. Some M are P.

The least possible Venn diagram for the given statement is:

Conclusions:

I. Some P are not J:

From Statement II, we know there is a portion of P that is M.

From Statement I, we know that nothing that is M can be J.

Conclusion I follows. 

II. Some P are M:

This conclusion is an immediate and definite inference (conversion) from Statement II (Some M are P).

The statement "Some A are B" can always be converted to "Some B are A."

Conclusion II follows.

So, Both conclusions I and II follows.

Hence, the correct answer is "Option 1".
