The logic behind the given patterns is:

D(+4) = H, H(+4) = L, L(+4) = P.

P(+4) = T, T(+4) = X, X(+4) = B.

R(+4) = V, V(+4) = Z, Z(+4) = D.

But,

J(+4) = N, N(+4) = R, R(+5) = W.

Hence, the correct answer is JNRW.

Hence, the correct answer is IGSH.

 As per the information provided in the question, we can make the following diagram

It is clear from the diagram that the man is 10 km towards west from the starting point.

As per the given information:

Rama is taller than Saho: Ram > Saho

Manoj is shorter than Dinesh: Manoj < Dinesh

Dinesh is taller than Tara but shorter than Saho: Saho > Dinesh > Tara > Kailash

So,

Kailash is shorter than Tara but taller than Manoj and Tara is shorter than Saho:

Rama > Saho > Dinesh > Tara > Kailash > Manoj

So, Manoj is the shortest.

The logic behind the series is:

9 x 3 + 3 = 30,

30 x 3 + 3 = 93

93 x 3 + 3 = 282

282 x 3 + 3 = 849

Hence, the correct answer is 849.

After carefully observing the figures given in the question, it is very clear that the answer figure(b) will be the missing figure.

Hence, the correct answer is:

The logic behind the series is:

C + 2 = E

E + 2 = G

G + 2 = I

I + 2 = K

And 9 + 7 = 16

16 + 9 = 25

25 + 11 = 36

36 + 13 = 49

So, the correct answer is K49.

We must choose intersection of Round and Table which is outside of Stone.

Hence, the correct answer is V.

Minimum Possible diagram is-

Conclusions:

I. All pens are plates. (It does not follow as its just a possibility, not surety.)

II. No plate is pen. (It also does not follow as Some pens are cups and All cups are plates.)

III. All cups are pens. (It also does not follow as Some pens are cups and All cups are plates.)

So, none follows.

The logic behind series is:

The logic for the first letter is:

C + 2 = E

E + 2 = G

G + 2 = I

The logic for the second letter is:

X – 2 = V

V – 2 = T

T – 2 = R

So, the next word is IR
