Select the set in which the numbers are related in the same way as are the numbers of the following sets.
(
NOTE:
Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 – Operations on 13 such as adding /deleting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
(63, 9, 27)
(105, 15, 45)
(149, 21, 63)
(149, 21, 65)
(147, 21, 65)
(147, 21, 63)
Correct answer
(147, 21, 63)
Why this answer is correct
The logic followed here is:
Logic: 2nd number × 3 = 3rd number. 2nd number × 7 = 1st number.
Now,
For (63, 9, 27):
⇒ 9 × 3 = 27
⇒ 9 × 7 = 63
For (105, 15, 45):
⇒ 15 × 3 = 45
⇒ 15 × 7 = 105
Similarly, for Option 4: (147, 21, 63)
⇒ 21 × 3 = 63
⇒ 21 × 7 = 147
Hence, the correct answer is Option 4.

÷, ×, –, =
Why this answer is correct
Given : 66 * 3 * 11 * 12 * 230
According to the question, after replacing the signs:
Option - (1): ×, –, =, ÷
66 * 3 * 11 * 12 * 230 ⇒ 66 × 3 - 11 = 12 ÷ 230
⇒ 66 × 3 - 11 = 12 ÷ 230
⇒ 198 - 11 = 0.05
⇒ 187 ≠ 0.05 (LHS ≠ RHS)
Option - (2): –, ×, ÷, =
66 * 3 * 11 * 12 * 230 ⇒ 66 - 3 × 11 ÷ 12 = 230
⇒ 66 - 3 × 11 ÷ 12 = 230
⇒ 66 - 3 × 0.92 = 230
⇒ 66 - 2.76 = 230
⇒ 63.34 ≠ 230 (LHS ≠ RHS)
Option - (3): ÷, ×, –, =
66 * 3 * 11 * 12 * 230 ⇒ 66 ÷ 3 × 11 - 12 = 230
⇒ 66 ÷ 3 × 11 - 12 = 230
⇒ 22 × 11 - 12 = 230
⇒ 242 - 12 = 230
⇒ 230 = 230 (LHS = RHS)
Option - (4): ×, –, ÷, =
66 * 3 * 11 * 12 * 230 ⇒ 66 × 3 - 11 ÷ 12 = 230
⇒ 66 × 3 - 11 ÷ 12 = 230
⇒ 66 × 3 - 0.92 = 230
⇒ 198 - 0.92 = 230
⇒ 197.08 ≠ 230 (LHS ≠ RHS)
Hence, "Option 3" is the correct answer.

Thus, the final series is:
Hence, "Option 2" is the correct answer.
Six letters, M, N, O, P, Q and R are written on different faces of a dice. Three positions of this dice are shown here. Find the letter on the face opposite N.
M
P
R
O
Correct answer
M
Why this answer is correct
The logic followed here is :-
From the given three different dices the adjacent sides are as shown below :
As N is common on both the dices I and III, it is clear that Q, O, P, and R are adjacent to it, and the remaining i.e. M will be opposite to it.
Opposite pairs:
O → P
Q → R
N → M
So, the opposite side of "N" will be side "M".
Hence, the correct answer is "Option 1".

Two statements are given followed by two conclusions numbered I and II. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements.
Statements:
All insects are birds.
Some birds are fishes.
Conclusions:
I. All fishes are insects.
II. Some fishes are insects.
Only conclusion II follows
Neither conclusion I nor II follows
Both conclusions I and II follow
Only conclusion I follows
Correct answer
Neither conclusion I nor II follows
Why this answer is correct
The least possible Venn diagram for the given statements is as shown below :
Conclusions:
I. All fishes are insects → Does not follow (As all insects are birds and some birds are fishes. So it is possible but not definite.)
II. Some fishes are insects → Does not follow (As all insects are birds and some birds are fishes. So it is possible but not definite.)
∴ Here, Neither conclusion I nor II follows.
Hence, the correct answer is "Option 2".

23 × 7 − 76 + 87 ÷ 344 = 2
× and ÷
÷ and =
× and −
Correct answer
÷ and =
Why this answer is correct
Given : 23 × 7 − 76 + 87 ÷ 344 = 2
According to the question, after interchanging the numbers:
Option - (1): × and ÷
23 × 7 − 76 + 87 ÷ 344 = 2 ⇒ 23 ÷ 7 − 76 + 87 × 344 = 2
⇒ 23 ÷ 7 − 76 + 87 × 344 = 2
⇒ 3.28 − 76 + 87 × 344 = 2
⇒ 3.28 + 29928 − 76 = 2
⇒ 29931.28 − 76 = 2
⇒ 29855.28 ≠ 2 (LHS ≠ RHS)
Option - (2): ÷ and =
23 × 7 − 76 + 87 ÷ 344 = 2 ⇒ 23 × 7 − 76 + 87 = 344 ÷ 2
⇒ 23 × 7 − 76 + 87 = 344 ÷ 2
⇒ 161 + 87 − 76 = 172
⇒ 248 − 76 = 172
⇒ 172 = 172 (LHS = RHS)
Option - (3): × and −
23 × 7 − 76 + 87 ÷ 344 = 2 ⇒ 23 - 7 × 76 + 87 ÷ 344 = 2
⇒ 23 - 7 × 76 + 87 ÷ 344 = 2
⇒ 23 - 7 × 76 + 0.25 = 2
⇒ 23 + 0.25 - 532 = 2
⇒ 23.25 - 532 = 2
⇒ -508.75 ≠ 2 (LHS ≠ RHS)
Option - (4): + and ×
23 × 7 − 76 + 87 ÷ 344 = 2 ⇒ 23 + 7 − 76 × 87 ÷ 344 = 2
⇒ 23 + 7 − 76 × 87 ÷ 344 = 2
⇒ 23 + 7 − 76 × 0.25 = 2
⇒ 23 + 7 − 19 = 2
⇒ 30 − 19 = 2
⇒ 11 ≠ 2 (LHS ≠ RHS)
Hence, "Option 2" is the correct answer.
