Select the odd group of numbers. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g.13 – Operations on 13 such as adding /subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)

Direction: Some equations have been solved on the basis of certain system. Find the correct answer for the unsolved equation on that basis.

6 × 2 × 9 = 269

8 × 7 × 1 = 781

4 × 1 × 3 = ?

Option

After interchanging the given two digits 4 and 6, what will be the value of the following equation?
 5 + 3 × 4 – 6 ÷ 2 = ? 

Which of the following numbers will replace the question mark (?) in the given series?
 11, 13, 29, 91, 369, ?

Directions: Study the following information carefully and answer the questions below.

Eight people- A, B, C, D, W, X, Y and Z are sitting in a circle facing the centre. All eight people are from different place i.e. Okhla, Dwarka, Lajpat Nagar, Chanakyapuri, Saket, Mehrauli, Rohini and Karol Bagh but not necessarily in the same order.

W is sitting third to the left of Y. The person who is from Dwarka is to the immediate right of W and W is not from Okhla. B is sitting fourth to the right of Z. Z is not the neighbour of Y. Neither B nor Z is an immediate neighbour of W. X is from Chanakyapuriand is sitting third to the right of the person from Dwarka. The person from Mehrauli is sitting second to the left of the person from Chanakyapuri. The person from Rohini is sitting second to the left of W. A who is Lajpat Nagar is sitting exactly between X and Z. The person from Saket is sitting second to the right of the person from Lajpat Nagar. C is sitting third to the left of X.

Four of the following five pairs are alike in a certain way based on their positions in the above arrangement and so from a group. Which of the following does not to the group?

Select the odd word/letters/number/number pair from the given alternatives.

. Option

The second number in the given number pairs is obtained by performing certain mathematical operation(s) on the first number. The same operation(s) are followed in all the number pairs, EXCEPT one. Find that odd number pair.
