Members: Dinesh, Soha, Mary, Raj.

Family chart,

Drawing the family tree as per the given information :

From the family tree, we get:

We do not know the gender of Soha.

Dinesh is the brother of Soha and Mary is the mother of Dinesh.

Mary is the wife of Raj.

So, Dinesh is the son of Raj.

Hence, the correct answer is "Son".

Here letters are written and below that sequence is mentioned. We have to check by options one by one to make meaningful English word.

1) 231645- ARVEST(This is not making any meaningful English word.)

2) 452316- STARVE(This is making a meaningful word which means die from hunger.)

3) 425316- SATRVE(This is not making any meaningful English word.)

4) 213654- AVRETS(This is not making any meaningful English word.)

Hence, correct option for this question is 2.

Here, we need to check the relationship and the pattern is:

First, we will check all the options:

1) Hut: A place where human lives.

2) Burrow: A place where rabbit lives.

3) Cobweb: A place where spiders live.

4) Den: A place where a lion lives. 

Thus, we can see that all the given words are places where animals are living except the word 'Hut'.

Hence, the odd one is 'Hut'.

The analogy is easy to decode. It is shown as follows:

(3²) + 2 = 11 or 9 + 2 = 11

Similarly,

(7²) + 2 = 51 or 49 + 2 = 51

Hence, ‘51’ is the correct answer.

Since, Krishnan is Dharun’s father (Kumar) father, he is his grandfather. Now, Anand is Dharun’s brother. Therefore, Anand is Krishnan’s grandson.

Hence, ‘grandson’ is the correct answer.

Explanation:

Preparing the family tree using the following symbols:

There is a family of five persons A, B, C, D, and E.

D is the father of B.

B is the wife of A.

C is the sister of D.

E is the wife of D

Tree Diagram:

According, to this "E is mother-in-law of A".

Hence, the correct answer is Mother-in-law.

Given,

Statements:

1. All kitchens are bedrooms.

2. No bedroom is a hall.

Explanation:

Venn Diagram:

Options:

1. Some bedrooms are kitchens ⇒ True
2. All halls are kitchens ⇒ False. ⇒ Because, all kitchens are bedrooms and No bedroom is hall.
3. No kitchen is a bedrooms ⇒ False. ⇒ Because, Some kitchens are bedrooms.
4. Some kitchens are halls ⇒ False. ⇒ Because, all kitchens are bedrooms and No bedroom is hall.

Hence, the correct answer is, "Some bedrooms are kitchens."

Given: Ant, Insect, Fox, Mammal

As, we know that Ant is an Insect and Fox is a Mammal.

Since, both ant and fox are not related to each other so it is represented separately.

Thus, the logical Venn diagram is:

Hence, 'option 2' is the correct answer.

It is true that nowadays, more people opt for fast food but the reason is not the complete explanation behind the assertion because some fast food prices are even more expensive than a normal healthy meal.

Hence, ‘ A is true, but R is false’ is the correct answer.

The logic followed is:

Check options on by one;

Interchange signs ‘+’ and ‘÷’ and numbers ‘2’ and ‘4’

1) 4 ÷ 2 + 3 = 6

After Replacing signs and numbers:

= 2 + 4 ÷ 3 

= 2 + 1.33

= 3.33 ≠ 6

2) 2 + 4 ÷ 3 = 3

After Replacing signs and numbers:

= 4 ÷ 2 + 3

= 2 + 3

= 5 ≠ 3

3) 4 + 2 ÷ 6 = 1.5

After Replacing signs and numbers:

= 2 ÷ 4 + 6

= 0.5 + 6

= 6.5 ≠ 1.5

4) 2 + 4 ÷ 6 = 8

After Replacing signs and numbers:

= 4 ÷ 2 + 6

= 2 + 6 

= 8

Hence, Option (4) is the correct answer.
