Let's check each option,

1) − × ÷ +

→ 17 - 7 × 12 ÷ 6 + 2 = 119

→ 17 - 7 × 2 + 2 = 119

→ 17 - 14 + 2 = 119

→ 19 - 14 ≠ 119

→ LHS ≠ RHS

2) + × − ÷

→ 17 + 7 × 12 - 6 ÷ 2 = 119

→ 17 + 7 × 12 - 3 = 119

→ 17 + 84 - 3 = 119

→ 101 ≠ 119

→ LHS ≠ RHS

3) × − ÷ +

→ 17 × 7 - 12 ÷ 6 + 2 = 119

→ 17 × 7 - 2 + 2 = 119

→ 119 - 2 + 2 = 119

→ 121 - 2 = 119

→ 119 = 119

→ LHS = RHS ⇒ Satisfies the logic.

4) + ÷ × −

→ 17 + 7 ÷ 12 × 6 - 2 = 119

→ 17 + 7/12 × 6 - 2 = 119

→ 17 + 7/2 - 2 = 119

→ 41/2 - 2 = 119

→ 37/2 ≠ 119

→ LHS ≠ RHS

Here, we can see that only Option 3 satisfies the logic.

Hence, the correct answer is "× − ÷ +".

The logic followed here is:

Logic: All the symbols given in the top of the image are shifting one place in each next image.

Hence, the correct answer is "Option 2".

Given Statements:

Some trees are fish.

All fishes are goats.

No goat is a flower.

The least possible Venn diagram for the given statement is:

Conclusions:

I. Some trees are goats - True (Because, Some trees are fish and all fishes are goats, so those part of fish that is trees is also goats).

II. Some fishes are not flowers - True (Because, All fishes are goats and No goat is a flower, so Some fishes are not flowers).

III. Some flowers are not goats - True (Because, No goat is a flower, so Some flowers are not goats).

So, All conclusions follows.

Hence, the correct answer is "Option 4".

The sitting arrangement as per the given information is as:

1. A sits to the immediate left of C and D is an immediate neighbour of C.

2. E sits third to the right of D and B is an immediate neighbour of both E and F.

Here, B sits to the immediate right of F.

Hence, the correct answer is "Option (3)".

The logic followed here is:

Logic: (2nd number + 3rd number) ÷ 2 - 101 = 1st number.

Now,

For (812, 879, 947)

→ (879 + 947) ÷ 2 - 101

→ 1826 ÷ 2 - 101 

→ 913 - 101 = 812.

For (648, 715, 783)

→ (715 + 783) ÷ 2 - 101

→ 1498 ÷ 2 - 101 

→ 749 - 101 = 648.

Similarly, for (612, 679, 747)

→ (679 + 747) ÷ 2 - 101

→ 1426 ÷ 2 - 101 

→ 713 - 101 = 612.

Hence, the correct answer is "Option 3".

Alternate Method

Logic: 1st number + 67 = 2nd number;

2nd number + 68 = 3rd number.

For (812, 879, 947)

→ 812 + 67 = 879

→ 879 + 68 = 947.

For (648, 715, 783)

→ 648 + 67 = 715

→ 715 + 68 = 783.

Similarly, for (612, 679, 747)

→ 612 + 67 = 679

→ 679 + 68 = 747.

Hence, the correct answer is "Option 3".

The embedded part of this image is:

Hence, the correct answer is "Option (1)".

The pattern followed here is:

Hence, the correct answer is "442".

The correct mirror image of the given figure is:

Hence, the correct answer is "Option 2".

Taking dice positions 5 as common,

Pair of opposite numbers:

3 - 6

5 - 2

4 - 1

So, the opposite number to 3 is 6.

Hence, the correct answer is "6".

Logic : (5), (4) and (3) is added to the first, second and third letter position value according to the English alphabetic series respectively. 

​So,

Hence, "HPA" is the correct answer.
