Reasoning PYQs

BODMAS Table:

letters to signs:

Given: 9 A 3 C 15 B 2 = ? D 10

Substituting the signs into the equation and using the BODMAS rule we get:

⇒ 9 ÷ 3 + 15 × 2 = ? − 10

⇒ 3 + 15 × 2 = ? − 10

⇒ 3 + 30 = ? − 10

⇒ 33 = ? − 10

 

⇒ 43 = ?

Hence, the correct answer is "Option 2"

The least possible Venn diagram for the given statements is:

(I) Some scooters are motors  - Follows ( All motors are scooters. Some scooters are motors and Some  motors are scooters)

(II) All fans are scooters - Follows (All fans are motors and all motors are scooters. Hence all fans are scooters)

Both conclusions (I) and (II) follow.

Hence, the correct answer is "Option 1"

The logic follows here, 

Logic: Second letter = First letter − 2, Third letter = Second letter − 3.

For QOL,

IGD,

GFB,

 For KIF,

Therefore, the letter cluster that is different from the others is GFB.

Hence, the correct answer is "Option 3"

The logic follows here,

Given word: BACKLOG.

The letter that appears exactly twice is B.

Hence, the correct answer is " Option 4"

The logic follows here, 

The missing term in the series is BEG.

The correct answer is option 4

The logic followed here is:

• 184 − 20 = 164
• 164 − 19 = 145
• 145 − 18 = 127
• 127 − 17 = 110
• 110 − 16 = 94
• **94 − 15 = **79

Hence, the correct answer is 'Option 4';

The logic follows here,

Logic: The difference between consecutive numbers in the series represents the cubes of consecutive natural numbers starting from 1.

• 9 + 1³ = 9 + 1 = 10
• 10 + 2³ = 10 + 8 = 18
• 18 + 3³ = 18 + 27 = 45
• 45 + 4³ = 45 + 64 = 109
• 109 + 5³ = 109 + 125 = 234

 

the missing number in the series is 10.

Hence, the  correct answer is "option 2"

The logic follows here, 

In the first code set yy ae wp and the second code set mr yy sf, the common code is yy.

Hence, the correct answer is "option 2"

Given series: 5 3 8 6 6 3 5 7 9 7 3 4 8 3 9 2 5 5 1 5 6 1 2 

Required Conditions: Even-Even-Even

 

Left   5 3 8 6 6 3 5 7 9 7 3 4 8 3 9 2 5 5 1 5 6 1 2  Right

Thus, there is only one such digit in the series - 8 6 6 

Hence, the correct answer is 'Option 1'.

Given: Seven boxes, L, M, N, O, P, Q and R, are kept one over the other, but not necessarily in the same order.

1. P is kept second from the top.
2. N is kept immediately before P.
3. Only M is kept after O.
4. R is kept immediately above O.

1. Only three boxes are kept between L and M.
2. Q is the only box remaining and will occupy the only vacant position.

Final Arrangement:

Thus, two boxes are kept between Q and M.

Hence, the correct answer is 'Option 3'.

The logic followed here is:

For PT - LG,

For  RF - NB,

For  MJ - IF,

For  UG - QC,

Therefore, the letter-cluster pair that is different from the others is PT - LG.

Hence, the correct answer is 'Option 1'.

The logic followed here is ,

For QAI,

 

For OGY,

For PHZ,

For KCU,

Therefore, the letter cluster that is different from the others is QAI.

Hence, the correct answer is 'Option 1'.

The logic followed here is,

 

Therefore, the code for J is 5.

Hence, the correct answer is "Option 2"

The least possible Venn diagram for the given statements is:

(I) Some apples are cups. - Doesn't follow (Their is no direct relation between apples and cups; maybe it is possible but not definite.)

(II) All cups are apples -  Doesn't follow (Their is no direct relation between apples and cups; maybe it is possible but not definite.)

Neither conclusion (I) nor (II) follows.

Hence, the correct answer is "Option 3."

The logic followed here is ,

Logic: The letters in the second cluster are obtained by subtracting 5 from the corresponding letters in the first cluster.

For XV-SQ,

For  US-OP,

 

For  TR-OM,

For PN-KI,

Therefore, the letter-cluster pair that is different from the others is US-OP.

Hence, the correct answer is 'Option 2'.

Given:  Seven people F, G, H, L, M, O and Q are sitting around a circular table, facing the centre of the table.

1. Only two people sit between Q and L when counted from the right of Q.
2. Only two people sit between L and O when counted from the left of O.
3. Only three people sit between Q and F when counted from the right of Q.
4. M sits to the immediate left of H.

The Final Arrangement is , 

H sits third to the left of G.

Hence, the correct answer is "Option 3"

The logic followed here is:

 

• 135 + 15 = 150
• 150 + 30 = 180
• 180 + 45 = 225
• 225 + 60 = 285
• 285 + 75 = 360

Thus, the missing term in the series is 360.

Hence, the correct answer is 'Option 1';

The logic followed here is:

Logic:

1) Second number = (First number)² + 1

2) Third number = First number + Second number

For the first set (2, 5, 7):

⇒ (2)² + 1 = 4 + 1 = 5 (Second number)

⇒ 2 + 5 = 7 (Third number)

For the second set (3, 10, 13):

⇒ (3)² + 1 = 9 + 1 = 10 (Second number)

⇒ 3 + 10 = 13 (Third number)

Applying the same logic to the set (6, 37, 43):

⇒ (6)² + 1 = 36 + 1 = 37 (Second number)

⇒ 6 + 37 = 43 (Third number)

Hence, the correct answer is 'Option 2'.

The logic followed here is,

• Mr. Yorly starts from Point A and drives 17 km towards East. He then takes a left turn, drives 18 km, turns left and drives 30 km.
• He then takes a left turn and drives 31 km.
• He then takes a left turn, drives 9 km, turns left and drives 6 km.
• He takes a final right turn, drives 4 km and stops at Point P

The Final Diagram , 

The required travel is 7 km to the North.

Hence, the correct answer is "option 2"

Given: Seven people, T, E, A, R, I, N, and G, are sitting in a row, facing north.

1. Only two people sit to the left of N.
2. Only three people sit between N and G.
3. Only one person sits between G and E.
4. I sits to the immediate left of R.
5. A is not an immediate neighbor of G

The final seating arrangement is:

From the arrangement, only G is sitting to the right of T.

Thus, there is One person sitting to the right of T.

Hence, the correct answer is "option 2"
