Logic follows:

For Vowel → Vowel - 1

For Consonant → Consonant + 1

Hence, DHM is the correct answer.

Mistake Point

One might misinterpret that positions are decreased and increased alternatively but if so then

EIL : DJK

Which is not the option.

Given,

Mistake Points

Shubham's house faces North.

He leaves from the back gate of his house which means he starts the journey in the south direction.

Now,

He leaves from the back gate of his house it means he starts the journeying south direction and walks 14 m.

Then he turns left and walks 30 m.

Then he turns left and walks 50 m.

Then he turns left and walks 10 m.

He then turns left and walks 36 m.

Here, we see Shubham is 20 m away in East direction from his home.

Study of birds is called Ornithology.

Similarly, Study of plants is called Botany.

Hence, “Botany” is the correct answer.

According to the given information-

1) P sits third left of Q who sits at the right end.

Hence, P sits second left of S.

So, the correct answer is P.

Important point

Concept:

1) We have to check the conclusions are 100% match with the statement. If the conclusion is 100% match with the given statement then the conclusion is true. If there is a 1% chance of not following the statement then the conclusion is considered to be false.

2) The possibility case can be considered to be "false" in "definite case".

3) In Possibility case, either "can" or "possible" word must be present.

The logic follows here is :-

The least possible Venn diagram for the given statements is as follows,

Conclusion:

I. Some Orange are White → True (Some White are Orange so that Some Orange are White is true).

II. Some Black are Orange → False (Some Black are White and Some White are Orange so that there is no relation for Some Black are Orange).

Thus, the correct answer is 'Only conclusion I follows'.

Additional Information

Correct Option - 3

The pattern followed here is:

Hence, "TVY" is odd among them.

Preparing family tree using following symbols:

Possible family tree diagram is as below:-

Neeru is Sahil's sister.

Hence, "Sister" is the correct answer.

Opposite surface of the open dice can be found by the below methods:-

• Alternate surface are opposite to each other.
• No two opposite surface are touched by side or by corners

So By using the above rule we can find the opposite surface of open dice.

Below are the opposite surfaces:-

As we know that, no two opposite surfaces are adjacent to each other.

So in option 1, @ and & are opposite surfaces but shown adjacent. Hence wrong.

In option 3, © and # are opposite surfaces but shown adjacent. Hence wrong.

In option 4, $ and % are opposite surfaces but shown adjacent. Hence wrong.

In option 2, no opposite surfaces are adjacent.

Hence, option 2 is correct.

The pattern for the code is as follows:-

The logic is as follows:

• 5² = 25
• 5³ = 125
• 10² = 100
• 10³ = 1000
• 15² = 225

Hence, 1000 is the answer.
