2)

The position of how many letters will remain unchanged if all the letters in the word BINDER are arranged in English alphabetical order?

3)

Select the combination of letters that when sequentially placed in the blanks of the given series will logically complete the series.

BYN_J_YNF_X_NFJVY_FJ

4)

Two sets of numbers are given below. In each set of numbers, certain mathematical operation(s) on the first number result(s) in the second number. Similarly, certain
mathematical operation(s) on the second number result(s) in the third number and so on. Which of the given options follows the same set of operations as in the given sets?

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

14 – 196 – 186 – 172; 15 – 225 – 215 – 200

5)

The same operation(s) are followed in all the given number pairs except one. Find that odd number pair.

(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 /deleting /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.)

6)

Which of the following numbers will replace the question mark (?) in the given series?

12, 25, 49, ?, 197, 395

7)

Four letter-clusters have been given, out of which three are alike in some manner and one is different. Select the one that is different.

Note : The odd one out is not based on the number of      consonants/vowels or their
position in the letter cluster

8)

What will come in place of the question mark (?) in the following equation, if ‘+’ and ‘–’ are interchanged and ‘×’ and ‘÷’ are interchanged?

164 – 173 ÷ 110 + 140 × 5 = ?

9)

What will come in the place of the question mark (?) in the following equation, if ‘+’ and
‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged?

304 × 19 − 101 + 23 ÷ 5 = ?

10)

In a certain code language,
R + T means ‘R is the sister of T’.
R – T means ‘R is the father of T’.
R * T means ‘R is the wife of T’.
R ÷ T means ‘R is the mother of T’.

Based on the above, how is M related to Q if ‘M * N – P + Q ÷ R +T’?
