Verbal Reasoning - Mental Ability Questions

Here the letter series is alternative reverse order series. So we get P, N.

Brother of mother — Uncle: Uncle's son — Cousin

The correct order is :

Population    Unemployment    Poverty     Disease   Death

          2                   4                             1                    5           3 

The given number sequence is 101, 98, 93, 86, 75, ?

101

101 - 3 = 98

98 - 5 = 93

93 - 7 = 86

86 - 11 = 75

75 - 13 = 62

Here the series follows a pattern that consecutive subtraction of prime numbers.

Hence, the next number in the sequence is 62.

Letters in the word           Letters in the alphabet

$$\begin{gathered} CHA \\ - - \end{gathered}$$                            $$\begin{gathered} CBA \\ - - \end{gathered}$$

$$\begin{gathered} RS \\ -- \end{gathered}$$                             $$\begin{gathered} RS \\ -- \end{gathered}$$       

The letter of the word are written in a reverse order and then each letter is moved one step backward to obtain the code.

T is the brother of S, who is the daughter of R. So, T and S are the children of R. 

Now. Q is the brother of R. So, T and S are the cousins of Q.
