BODMAS Table: 

‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged

Given Equation: 39 − 15 ÷ 3 + 124 × 4

After interchanging: 39 + 15 × 3 − 124 ÷ 4, using the BODMAS rule:

= 39 + 15 × 3 − 124 ÷ 4

= 39 + 15 × 3 − 31

= 39 + 45 − 31

= 84 − 31

= 53

Hence, the correct answer is "option 2"

The logic followed here is:

Logic: Third Number = (First Number + Second Number) + 10

For the first set (15, 12, 37)

⇒ (15 + 12) + 10

⇒ 27 + 10 = 37.

For the second set (25, 15, 50)

⇒ (25 + 15) + 10

⇒ 40 + 10 = 50.

Applying the same logic to the options:

(2, 8, 20)

⇒ (2 + 8) + 10

⇒ 10 + 10 = 20.

Hence, the correct answer is 'Option 1'.

The logic followed here is.

Combining the results from each letter position, the next term in the series is PNP.

Hence, the correct answer is "option 1"

Given: Seven people, F, G, H, L, M, O, and Q, are sitting in a row facing north.

1. Only two people sit between H and Q.
2. Only H sits to the right of G.
3. Only three people sit between G and F.
4. L sits at some place to the left of O, but at some place to the right of M.

The Final Arrangement is, 

Number of people sit between M and O is 3

Hence, the correct answer is "Option 3"

The logic follows here. 

Thus, the code for the letter T is 8.

Hence, the correct answer is "option 3"

The shaded part shows, such Consultants are there who are Bankers as well as Advocates​

Thus, there are 32 consultants who are bankers as well as advocates.

Hence, the correct answer is "option 1"

The logic followed here is ,

Logic: 1^st Letter − 3 = 2^nd Letter; 2^nd Letter + 1 = 3^rd Letter.

For ZWX,

For PNN,

For FCD,

For KHI,

Therefore, the letter cluster that does not belong to the group is PNN.

Hence, the correct answer is 'Option 2'.

Given: Seven boxes A, B, C, D, E, F, and G are kept one over the other but not necessarily in the same order.

1. Only two boxes are kept between G and B.
2. Only D is kept above C.
3. No box is kept below B.
4. F is kept at some place below A but at some place above E.

The Final Arrangement is, 

Four boxes are kept between D and E.

Hence, the correct answer is " Option 3"

The least possible Venn diagram for the given statements is:

(I) Some flowers are doors -  Doesn't follow

(There is no direct relation between flowers and doors; maybe it is possible but not definite. Hence, it is false)

(II) All petals are flowers - Doesn't follow (Some petals are flowers, and some flowers are petals. Hence, it is false)

Neither conclusion (I) nor (II) follows.

Hence, the correct answer is "Option 2"

The logic followed here is:

• 211 + 8 = 219
• 219 + 16 = 235
• 235 + 24 = 259
• 259 + 32 = 291
• 291 + 40 = 331

Thus, the missing term in the series is 331.

Hence, the correct answer is 'Option 2';
