Reasoning PYQs

The least possible Venn diagram for the given statements is as shown below :

Conclusions:

Option 1) No plants are flowers → Does not follow (As all flowers are plants. As whole flowers comes in plants, therefore it is false.)

Option 2) Some flowers are not plants → Does not follow (As all flowers are plants. As whole flowers comes in plants, therefore it is false.)

Option 3) Some plants are flowers → Follow (As all flowers are plants. As whole flowers comes in plants, therefore it is True.)

Option 4) All plants are flowers → Does not follow (As all flowers are plants. As whole flowers comes in plants, so it is possible but not definite)

∴ Here, Only conclusion 3 follows.​

Hence, the correct answer is "Option 3".

Given: In a race of 40 runners, if Anu is placed 15^th.

Total runners = 40

Anu's position = 15

Runners are ahead of Anum → Anu's position - 1

→ 15 - 1 = 14​

Hence, the correct answer is "Option 1".

The logic followed here is:

DREAM: GRDBM

Similarly,

MAGIC:?

Hence, "Option 3" is the correct answer.

The logic that is followed in the given steps is given as follows:

1. Word are arranged in descending order according to the English dictionary order i.e. in reverse alphabetical order right end.

2. Number are arranged in descending order from the left end.

3. In each step only alternately one number and one word is shifted, starting with the number.

Thus, Numbers descending left; words in reverse alphabetical order right.

Hence, "Option 4" is the correct answer.

Given: 

3 men and 2 women are seated in a row.

Two particular woman does not sit together

Formula:

Ways of arranging n distinct things taken all at a time = n!

Explanation:

Arranging the 3 men = 3! → (3 × 2 × 1) ⇒ 6

Now, with the 3 men placed, there are 4 gaps there are four gaps where women can sit and as two woman cannot sit together, therefore = 4C2 = 6

The two woman can be arranged in = 2! → (2 × 1) ⇒ 2 ways

So, the number of ways can 3 men and 5 men are seated in a row so that no woman is seated next to another woman =  6 × 6 × 2 ⇒ 72

Hence, "Option 4" is the correct answer.

The logic followed here is:

Hence, "Option 2" is the correct answer.

Decoding symbols:

Given: P x Q - R

P x Q → P is the father of Q.

Q - R → Q is the sister of R.

Thus, P is the father of Q and Q is the sister of R

Hence, the correct answer is "Option 1"

Given: Four friends X, Y, Z, and W each have some marbles.

Let the number of marbles X has → x

Let the number of marbles Y has  → y

Let the number of marbles Z has → z

Let the number of marbles W has → w

1. X gives Y as many marbles as he already has, gives Z twice the amount of marbles Z already has, and gives W thrice the amount of marbles W already has.

2. Then, W gives 1/6^th of his marbles to Y. Afterward, X gives 10% of the marbles he now owns to Z and 20% to Y. Finally, all of them have 50 marbles each.

1/6^th of W's marbles will be → 4w × 1/6 = 2/3w

10% of the X's marbles will be → 10% of (x - y - 2z - 3w) = 0.1(x - y - 2z - 3w)

20% of the X's marbles will be → 20% of (x - y - 2z - 3w) = 0.2(x - y - 2z - 3w)

So, solving for each of them:

For X: 0.7(x - y - 2z - 3w) = 50 ------- (1)

For Y: 2y + 2/3w + 0.2(x - y - 2z - 3w) = 50 ------- (2)

For Z: 3z + 0.1(x - y - 2z - 3w) = 50 ------- (3)

For W: 10/3w = 50 ------- (4)

In equation 4 we get:

10/3w = 50

w = 50 × 3/10

w → 15

In equation 1 we get:

0.7(x - y - 2z - 3w) = 50 → (x - y - 2z - 3w) = 50/0.7

Putting the value in equation 2 we get:

2y + 2/3w + 0.2(x - y - 2z - 3w) = 50 → 2y + (2/3 × 15) + 0.2(50/0.7) = 50

→ 2y + 10 + 100/7 = 50

→ 2y + (2/3 × 15) + 0.2(50/0.7) = 50

→ y = 90/7

Putting the value in equation 3 we get:

3z + 0.1(x - y - 2z - 3w) = 50 → 3z + 0.1(50/0.7) = 50

→ 3z + (50/7) = 50

→ z = 100/7

Putting the value of w, y and z equation 1 we get:

→ 0.7(x - y - 2z - 3w) = 50

→ x = 50/0.7 + y + 2z + 3w

→ x = (50/0.7) + (90/7) + (2 × 100/7) + (3 × 15)

→ x = 1105/7

Thus, the original number of marbles each friend had was:

X = 1105/7

Y = 90/7

Z = 100/7

W → 15

Hence, "Option 4" is the correct answer.

According to the question:

Address 1: Ms. Neha Verma, Flat No. 204, Tower B, Green Acres, Pune 411045

Address 2: Mrs. Neha Verma, Flat No. 204, Tower B, Green Acres Society, Pune - 411045

Thus, No, the name titles are different.

Hence, "Option 4" is the correct answer.

Additional InformationNo, city codes do not match → False, as the city codes match

Yes, all details match except name titles → False, as the word 'Society' also does not match

No, the flat numbers are different → False, as the flat number are same.

The logic followed here is:

Hence, "Option 1" is the correct answer.

Given:

A person is facing north.

He walks 30 meters and turns to his right, walking 20 meters.

Then, he turns to his left and walks 30 meters.

Thus, facing in the north direction now.

Hence, "Option 4" is the correct answer.

The logic followed here is:

A. BRIGHT: DSJHF

B. CUSTOM: EVTUM

C. FLIGHT: HMJHF

D. CHANCE: EIBOA

E. STRONG: VUQPR

Thus, out of all STRONG: VUQPR is the odd one out.

Hence, "Option 1" is the correct answer.

The conditions for the selection of a professor in a college are as follows:

Thus, Sahil Can be recruited as college professor

Hence, "Option 4" is the correct answer.

Given:

4 people are seated in a circle.

2 people sit next to each other

Formula:

Ways of arranging n distinct things taken all at a time = n!

Explanation:

So, the number of ways 4 people be seated in a circle if two people must sit next to each other = 2! × 2 ⇒ 4

Hence, "Option 4" is the correct answer.

According to the question:

Here, no example Input - output is given, therefore pattern for the given input cannot be determined.

Hence, "Option 4" is the correct answer.

Given:

You are facing east and move 10 meters, then turn to your left and move 5 meters.

Thus, facing in the north direction now.

Hence, "Option 2" is the correct answer.

According to the question:

1. P is taller than only T.

_ >_ > _ > P > T

2) Q is taller than P but shorter than R.

3) S is the tallest.

S > R > Q > P > T

Thus, T is the shortest.

Hence, "Option 2" is the correct answer.

Given:

Total mixture = 50 L

Milk : Water = 3 : 2

Target ratio = 1 : 1

Formula used:

Total parts = 3 + 2 = 5

Milk = Total × (Milk part ÷ Total parts)

Water = Total × (Water part ÷ Total parts)

For 1:1 ⇒ Final water = Milk

Calculations:

⇒ Milk = 50 × 3 ÷ 5 = 30 L

⇒ Water = 50 × 2 ÷ 5 = 20 L

⇒ Required water for 1:1 = 30 L

⇒ Water to add = 30 − 20 = 10 L

∴ Add 10 L water.

In all the other figures, every row has only one circle inside it.

Hence**, "Option 3"** is the correct answer.

Given: 

1. X is the father of Y

2. Y is the mother of Z

Thus, X is Z's grandfather.

Hence, the correct answer is "Option 3"
