The logic followed here is:

Logic: The second word is commonly found or housed in the first word.

Here,

Garage : Bike → A bike is commonly found or housed in a garage.

Similarly,

Aquarium : Fish → Fish is commonly found or housed in an aquarium.

Hence, the correct answer is "Fish".

Given:

(8, 388, 18)

(11, 137, 4)

Logic: Second no. = [(First no.)² +(Third no.)²]

(8, 388, 18) →

⇒ [(8)² + (18)²]

⇒ (64 + 324) = 388

(11, 137, 4) →

⇒ [(11)² + (4)²]

⇒ (121 + 16) = 137

Checking all the given options:

1. (15, 230, 2) →

⇒ [(15)² + (2)²]

⇒ (225 + 4) = 229

2. (3, 51, 7) →

⇒ [(3)² + (7)²]

⇒ (9 + 49) = 58

3. (10, 118, 9) →

⇒ [(10)² + (9)²]

⇒ (100 + 81) = 181

4. (14, 221, 5) →

⇒ [(14)² + (5)²]

⇒ (196 + 25) = 221

Here, (14, 221, 5) shows a similar relation to the given set of numbers.

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

The correct mirror image of the given figure when the mirror is placed at AB is shown below:

Hence, 'option 3' is the correct answer.

Here, we need to find the pattern to get the missing number.

The logic here is: The odd terms are subtracted by 8 to get the next odd term and each even terms are added by 8 to get the next even numbers.

Hence, the missing number is "644".

The number of cycles which are not pedals = (6 + 5) = 11

Hence, the correct answer is "11".

Mistake Points

cars We will not consider car while solving this problem because the question has not mentioned about cars

The logic followed here is:

Logic: (Sum of the place value of all numbers)² + 1 = Code of the word.

'BED' is written as '122'

⇒ (2 + 5 + 4)² +1

⇒ 11² + 1 = 122.

'CAB' is written as '37'

⇒ (3 + 1 + 2)² +1

⇒ 6² + 1 = 37.

Similarly, for 'ADD'

⇒ (1 + 4 + 4)² +1

⇒ 9² + 1 = 82.

So, 'ADD' will be written as '82'.

Hence, the correct answer is "82".

Given:

Only three notebooks are kept between Chemistry and Physics notebooks.

Only Biology notebook is kept between Mathematics and Geography notebook.

Hindi notebook is kept at the bottom-most position.

The final arrangement will be:

Therefore, the Biology notebook is kept at the third position from the top.

Hence, the correct answer is "option 4".

The position and positional values of English Alphabets are:

The logic followed here is: Each Vowel of the word is increased by 1 and each consonant of the given word is decreased by 1.

So, TEST will be SFRS.

Hence, the correct answer is 'Option 3'.

Statement:
It is reported that heavy and erratic rainfall has destroyed many agricultural crops and farmers are in debt.

Conclusions:
I. Farmers need not repay the debt → Does not follow → From the given statement there is no information that tells us about the repayment of debt so we cannot assume anything so the conclusion does not follow.

II. Prices of groceries and other essential food items such as lentils and grains will surge → Follow → Since the farmers are in debt and their crops has been destroyed, there will be an increase in the price of upcoming crops by the farmers so that they can make a good amount of money to pay their debt, we can see that this conclusion directly justifies the statement, therefore, the conclusion follow.

So only conclusion II follows.

Hence the correct answer is option 4)

The least possible venn diagram as per the given statements:

Conclusions:

I. All registers are grills → Not Follows (Because, some registers are markers, and no grill is a marker)

II. No marker is a grill → Follows (Because no grill is a marker)

Hence, the correct answer is "Only conclusion II follows".
