The logic followed here is:

Consider A as Plus.

Then,

14 A 13 A 3 = 30

→ 14 + 13 + 3 = 30.

and,

39 A 14 A 3 = 56

→ 39 + 14 + 3 = 56.

Similarly,

28 A 11 A 4 = ?

→ 28 + 11 + 4 = 43.

Hence, the correct answer is "43".

Given:

Statement:

Essay writing is an art. It requires an understanding of the subject as well as a command over the language to be able to write a good essay.

Assumptions:

I. Essays cannot be written without complete mastery over the subject → False (As it requires an understanding of the subject as well as a command over the language to be able to write a good essay. It is not necessary to have mastery over the subject to write an essay.)

II. Anyone with a good command over the language write a good essay → False (Good command over the language is one of the important requirements but subject understanding is also required to write a good essay.)

Hence, the correct answer is  'Neither assumption I nor II is implicit '.

The logic followed here is:

Logic: The first term in each pair is the capital city of the country represented by the second term.

Option 1) New Delhi – India → New Delhi is the capital of India.

Option 2) Beijing – China → Beijing is the capital of China.

Option 3) Dhaka – Bangladesh → Dhaka is the capital of Bangladesh.

Option 4) Lahore – Pakistan → Lahore is not the capital of Pakistan, The capital of Pakistan is Islamabad.

Hence, the correct answer is "Option 4".

The correct mirror image of the given figure when the mirror is held at the right side is:

Hence, "option (4)" is the correct answer.

Additional Information

In Mirror image left side and right side changed vice-versa where top and bottom remain same.

Reflection of an object into the water is its water image. It appears by inverting an object vertically i.e. upside down.

The water image of the figure looks like the mirror image of the figure in case the mirror is horizontally at the bottom of the figure.

Water image is just a reflection where top and bottom part of the images changed where left and right side of the image remain same.

Mistake Points

Even though

2nd and 4th figure looks similar, there is a difference.

2nd Figure

Given:

Statement:

Eating foods which have been heated in plastic containers causes cancer, therefore it should be avoided.

Assumptions:

(I) Only storing food in plastic containers is not harmful for health - False (Nothing mention about the storing food in the statement, so it does not followed).

(II) Non-plastic containers which can be used to heat food are available - True (There is clearly mention plastic containers should be avoided, it gives the other containers will be available in the market to store food).

So, Only assumption II is implicit.

Hence, the correct answer is "Option 1".

The logic followed here is:

Logic: The first term is a place or enclosure where the second term lives or is kept.

Now,

Aquarium : Fish → An aquarium is a place where fish are kept.

Similarly,

Hive : Honeybee →  hive is a place where honeybees live.

Hence, the correct answer is "Option 1".

Additional Information

Aeroplane : Hangar → A hangar is a place where aeroplanes are stored, not where they live.

Wine : Cellar → A cellar is a place where wine is stored, not where it lives.

Animals : Zoo → A zoo is a place where animals are kept.

The logic followed here is:

Option 1) LMNO

Here, All the options except 'BDEF' followed a pattern.

Hence, the correct answer is "Option 4".

The logic followed here is:

So, '114' will complete the series.

Hence, the correct answer is "114".

The logic followed here is:

Logic: (1st number - 2)² = 2nd number.

Now,

11 : 81

→ (11 - 2)² ⇒ 9² = 81.

22 : 400

→ (22 - 2)2 ⇒ 202 = 400.

Similarly, for ? : 225

→ (17 - 2)2 ⇒ 152 = 225.

Hence, the correct answer is "Option 3".

Given:

Some goats are books.

All books are chairs.

Solutions:

The least possible Venn diagram is:

Conclusions:

I. Some books are chairs - Follows (As all books are chairs than some books will be chairs)

II. Some chairs are goats - Follows (As we know some goats are books and all books are chairs than some chairs will be goats)

Hence, the correct answer is "option (4)".
