Reasoning PYQs

Given,

Actual cost of book = 40/-

But,

The book which costs Rs. 40 is sold for 25% profit.

⇒ Actual cost of book + 25% profit of the book.

= 40 + (40 × 25) ÷ 100

= 40 + 10

= 50/-

The actual cost of the book with 25% = 50/-

⇒ If the cost of the book is increased by 10% and profit percentage remains the same,

New selling price = Actual cost of book with 25% profit + Cost of book increased by 10%

New selling price = 50 + ((50 × 10) ÷ 100)

New selling price = 50 + 5

New selling price = 55/-

∴ Here, the new selling price of the book is 55/-

Hence, the correct answer is "Rs. 55".

The correct mirror image of the given combination when the mirror is placed at PQ is as shown below:-

Hence, the correct answer is "Option 3".

The logic followed here is :-

Hence, the correct answer is "20".

Given,

Total number of students in class = 64 students

Komal’s rank is 6 positions lower (i.e. towards bottom) than her friend Shikha, who is at the 59^th position from the end. 

 

Position of Komal from bottom = Position of Shikha - 6 = 59 - 6 = 53,

Position of Komal = Number of students - Position of Komal from bottom + 1

Position of Komal = 64 - 53 + 1

Position of Komal = 65 - 53

Position of Komal = 12^th position.

Hence, the correct answer is "12^th".

After unfolding the given paper the image formed is as shown below :

Hence, the correct answer is "Option 1".

Preparing the family tree using the following symbols:

According to the given information,

The given expression is :

'U $ Q & Y % D $ S # K' → U is mother of Q, Q is sister of Y, Y is brother of D, D is mother of S, S is wife of K.

 

1) D is the mother-in-law of K → True (As D is mother of S and S is wife of K so, D is the mother-in-law of K is true)

2) Q is the sister of D → True (As Q is sister of Y and Y is brother of D so, Q is the sister of D is true)

3) Y is the daughter of U → False (As Y is brother of D so Y is a male. Hence, Y is the daughter of U is false)

4) U is the mother of D → True (As U is mother of Q and Q is sister of Y and Y is brother of D so, U is the mother of D is true)

Hence, the correct answer is "Y is the daughter of U".$

The logic followed here is :-

OESTD : UAVXI

 

Similarly,

UISRY : ? 

Hence, the correct answer is "AEVVD".

The logic followed here is :-

1) A is taller than B and E is shorter than B but taller than D.

A > B > E > D

2) C and D are of equal height.

A > B > E > D = C

3) F is shorter than C, who is shorter than B.

A > B > E > D = C > F

∴ Here, 'F' is the shortest among all.

Hence, the correct answer is "F".

Preparing the family tree using the following symbol:

Family Tree :-

∴ Here, Benkat is 'father' of Rahul.

Hence, the correct answer is "Father".

The logic followed here is :-

Tamanna is walking towards the north from her house. After 500 metres she turns left and walks for 500 metres. Then she turns left and walks 250 metres to reach her friend’s house.

∴ Here, Tamanna's house is in south-east from her friend's house.

Hence, the correct answer is "South-East".

P, Q, R, S, T and U are six friends sitting at equal distances from each other around a circular table facing the centre of the table.

1) U is sitting at the 4^th position to the left of T.

 

2) R is sitting to the immediate left of U.

 

3) Someone is sitting between S and T but it’s not P.

 

∴ Here, 'P' is sitting opposite of 'T'.

Hence, the correct answer is "P".

The logic followed here is :-

The given words represent the process of printing information present in a document file which is present in a computer.

Select the content from the source → Copy the content → Paste the content in a file → Save the file → Print the saved file

5. Select 
6. Copy
7. Paste
8. Save

Hence, the correct answer is "5, 2, 1, 3, 4".

The logic followed here is :-

1) BKYP

2) GDTW

3) SXHD

 

4) XJCQ

 

∴ Here, 'SXHD' is different from other three alternatives.

Hence, the correct answer is "SXHD".

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

Conclusions:

I. Some chairs are goods → True (As Some chairs are beds and All beds are goods so, Some chairs are goods is true)

Il. Some goods are not beds → False (it is possible but not definite)

∴ Here, Only conclusion I is true.

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

The logic followed here is :-

Hence, the correct answer is "141".

In the given word the letters alphabet positional value opposite -1.

GKNR : SOLH

Similarly,

MNGB : ? 

Hence, the correct answer is "MLSX".

The logic followed here is :-

By using BODMAS RULE :

The given expression : 5 ÷ 3 < 2 + (9 + 3) × 2 = ? 

After interchanging the symbols by mathematical operators the expression is as follows : 5 + 3 × 2 ÷ (9 ÷ 3) - 2

= 5 + 3 × 2 ÷ (9 ÷ 3) - 2

= 5 + 3 × 2 ÷ 3 - 2

= 5 + 3 × 0.66 - 2

= 5 + 2 - 2

= 7 - 2

= 5

Hence, the correct answer is "5".

Given,

The sum of the scores obtained by Ram and his two friends in an exam is 60% of the sum of the maximum marks for the exam for all three of them

The ratio of their obtained marks is 4 ∶ 5 ∶ 6

Ratio of Ram : Ram's first friend : Ram's second friend = 4 : 5 : 6

Let the sum of maximum marks for the exam for all three of them = 3M

Total sum of marks obtained = 4x + 5x + 6x

Total sum of marks obtained = 15x

Sum of the scores obtained by Ram and his two friends in an exam is 60%.

Total sum of marks obtained = Sum of the scores obtained by Ram and his two friends in an exam is 60% of the sum of the max marks

⇒ 15x = 60% × 3M

⇒ x = 4% × 3M

⇒ x = \({3M \over 25}\)

⇒ Percentage of marks scored by Ram = ((4 × \({3M \over 25}\) ) ÷ M) × 100

Percentage of marks scored by Ram = \({12 \over 25}\) × 100

Percentage of marks scored by Ram = 48%

⇒ Percentage of marks scored by Ram's first friend = ((5 × \({3M \over 25}\) ) ÷ M) × 100

Percentage of marks scored by Ram's first friend = \({15 \over 25}\) × 100

Percentage of marks scored by Ram's first friend = 60%

⇒ Percentage of marks scored by Ram's second friend = ((6 × \({3M \over 25}\) ) ÷ M) × 100

Percentage of marks scored by Ram's second friend = \({18 \over 25}\) × 100

Percentage of marks scored by Ram's second friend = 72%

∴ Here, Only Ram's second friend has scored more than 70% i.e., 72%

Hence, the correct answer is "One".
