Verbal Reasoning - Mental Ability Questions

Arithmatic mean = sum/members 

=> (1x1 + 2x2 + 3x3 + 4x4 + 5x5 + 6x6 + 7x7) / (1 + 2 + 3 + 4 + 5 + 6 + 7)

=> 140/28 = 5

As given, we have:

Susmitha > Laxmi > Ramya; Ramya = Hema, Ramya > Avanthi

Thus the sequence of heights becomes:

Susmitha > Laxmi > Ramya = Hema > Avanthi

Clearly, Hema is shorter than Laxmi.

Given Number :  7 6 5 3 4 2 1 8 

New Number :    8 7  6 4 5 3 2 9

Ascending Order :  2 3 4 5 6 7 8 9 

Fifth digit in the above ascending order arrangement is '6' . Hence option(1) is the correct answer.

Second is a bony protective covering for the first. Here pericardium protects Heart and Cranium protect Brain.

Hence, Heart : Pericardium :: Brain : Cranium.

Given word : CONTEXTUAL

After making changes as per given in the question , the above word becomes as follows:

XTUALCONTE . Hence, 4th letter from the right end is O.

quicker method:

    Total no of letters in the given word = 10.

    4th letter from the right means (10 - 4 + 1 =) 7th letter from the left of the word obtained after rearrangement. Again, read the question , we come to know that, the positions of the second and seventh letters are interchanged. Hence the required letter is the second letter of the given word which is O.

All males are Human beings so the circle for male come in between human being; and all fathers are male so the circle for fathers comes in between the male circle. So, option C suits best.
