Search Previous Year Questions

According to the question:

1. The age of a father is twice the sum of the ages of his 3 children.

2) After 15 years, his age will be equal to the sum of the ages of his children.

Let the age of the father be = F

Let the age of the 3 children be = C1, C2 and C3

So, 

F = 2 (C1 + C2 + C3) --------- (1)

After 15 years,

F + 15 = (C1 + 15) + (C2 + 15) + (C3 + 15)

F + 15 = (C1 + C2 + C3) + 45

F = (C1 + C2 + C3) + 30 ------------- (2)

From (1) and (2), we get

F = (F ÷ 2) + 30

2F = F + 60

F = 60

Thus, father's ager after 15 will be:

F = 60 + 15 = 75 years

Hence, "Option 4" is the correct answer.

1. INDUCTIVELY → can be formed

2. JUVENILITY → can be formed

3. INDUCTED → cannot be formed as there is only single D in DISJUNCTIVELY.

4. DECLIVITY → can be formed

Hence, INDUCTED cannot be formed from the letters used in DISJUNCTIVELY.

All options except 'Jharkhand' are name of capital cities of different states in India, while 'Jharkhand' is the name of a state in India.

Hence, ‘Jharkhand’ is the odd one out.

This is an alternate number series .

It follows the following pattern :

Hence, the correct answer is 16 .

Statements:

No pen is a pencil.

All pencils are chalks.

The least possible diagram for the given statements is as follows

Conclusions:

I. No chalk is a pen → False (It is possible but not definite)

II. No pencil is a pen → True (because no pen is a pencil so definitely no pencil is a pen)

III. Some chalks are pencils → True (because all pencils are chalks so some chalks are definitely pencils)

Hence, “Only conclusions II and III follow” is the correct answer.

BODMAS Table: 

Given equation I. 7 - 5 + 1 × 3 ÷ 6 = 20

Now, if '1 and 6' are interchanged, then:

⇒ 7 - 5 + 6 × 3 ÷ 1 = 20

⇒ 7 - 5 + 6 × 3 = 20

⇒ 7 - 5 + 18 = 20

⇒ 25 - 5 = 20

⇒ 20 = 20

LHS = RHS.

Given equation II: 1 × 7 + 6 - 4 ÷ 2 = 40

Now, if '1 and 6' are interchanged, then:

⇒ 6 × 7 + 1 - 4 ÷ 2 = 40

⇒ 6 × 7 + 1 - 2 = 40

⇒ 42 + 1 - 2 = 40

⇒ 43 - 2 = 40

⇒ 41 ≠ 40

LHS ≠ RHS.

Here, Only Equation I are the correct after interchanging the given symbol.

Hence, the correct answer is "Option 1".

The logic followed here is:

Consonants coded as the next letter and vowels remain the same vowels.

Similarly,

Therefore,

Hence, the correct answer is "GIOHES".

The pattern followed here is:

Given: Seven people A, H, D, F, T, E, and G are sitting in a straight row, facing north.

1) Only three people sit to the left of E.

(It means E sits on the middle of the row)

2) A sits at the extreme right of the row.

3) F sits second to the left of E.

4) G and H are immediate neighbours of E.

(Position of G and H is not clear but they sit either side of E)

5)  D is the immediate neighbour of A.

6. So, T sits on the vacant place.

Clearly, T sits extreme left of the row.

Hence, the correct answer is "T".

The Venn diagram that best represents the relationship between Saturn, Planet, and Cadminum is shown below:

Saturn is a Planet and Cadmium is a chemical element.  

Hence, ‘option 1’ is the correct answer.

To form the code, the first letter is replaced by its predecessor, the second letter is replaced by its successor, the third letter is replaced by its second predecessor, the fourth letter is replaced by its second successor and so on as per the English alphabetical series.

Similarly,

Hence, MARKET will be coded LBPMBW.
