Directions (Q. 4-5): Study the following information carefully to answer the given questions.
A + B means 'A is mother of B'.
A - B means ' A is father of B ' .
A x B means 'A is husband of B'.
A + B means 'A is daughter of B'.

If Px S + T - V , then how is V related to P ?

Answer & Explanation

Answer : Option
D
Explanation :
V's gender is not specified, so may be either brother-in-law or sister-in-law.

5.

Which symbols should come in place of question mark (?) respectively in order to make the ralation 'R is daughter-in-law of T and W is grand mother of Z ?

T ? W + C x R ? Z

Answer & Explanation

Answer : Option
B
Explanation :
T must be husband of w and R must be mother of Z.

6.

In Which of the following expressions, X > Z as well as Z < Y is true ?

Answer & Explanation

Answer : Option
D
Explanation :
Chech for (1) :

X > V > Z = R < C < Y

Comvining

X > V > Z < C < Y

Combining

So (1) is not true for the given condition.

Check for (2) :

X > V > Z = R < C < Y

Combining

X > Z < Y

So, this expression is also false.

Check for (3) :

X < V > Z = R < C < Y

Comparison is not possible.

So, this is also not true.

Check for (4) :

X > V > Z = R < Y < C

Combining

X > Z = R < Y < C

Combining

X > Z < Y < C

So, both conditions are true for this expression.

7.

Which symbol should come in place of question mark in order to make the ralations Q < L and S < M definitely true in the following expression ?

P > Q ? S = L ? N < M

Answer & Explanation

Answer : Option
A
Explanation :
Check for (1) :

P > Q < S = L < N < M

Combning

P > Q < L < N > M

So, (1) is not true because of < similarly 2 is also not true.So, now we check for (3).

P > Q < S = L < N < M

Combining

P > Q < L < N < M

Thus Q < L holds true for this

Agains check

P > Q < S = L < N > M

P > Q < S < N < M

So, S < M also holds true.

Therefore option (3) is the right choice.

Now,

Check for (4) :

P > Q < S = L < N < M

Combining

P > Q < S = L < M

S < M

So, (4) isn not right choice

8.

Which of the following expressions does not lead to P > S and R < L being definitely true ?

Answer & Explanation

Answer : Option
C
Explanation :
Check for (1) :

P > K > S < R < M < L

Combining

P > S < R < L

So, this expression is true.

Check for (2) :

P > K = S < R = M < L

Combining

P > S < R < L

So, this expression is also true.

Check for (3) :

P < K > S = R < M < L

No relation combining

S = R < L

Thus this expression does not fit.

Check for (4) :

P > K > S = R < M < L

Combining

P > K > S = R < M < L

Combining

P > S = R < L

So, this expression is true for the given conditions.

9.

In which of the following expressions, P = S and R < M are definitely true ?

Answer & Explanation

Answer : Option
A
Explanation :
Check for (1) :

P > T > S = R < N < M

Combining Combining

P > S = R < M

So, the given statement are is true in this expression.

Check for (2) :

P > T < S = R < N < M

Combining Combining

is not possible R > M

but can't say, P = S

because if T = 6

and P = 8, S = 8

then also P > T < S

8 > 6 < 8 holds true.

Thus can't say exactly P = S

Therefore conditions not satisfied.

Check for (3) :

P = T < S > R > N < M

P < S > R > N < M

Thus R < M does not hold true here.

Check for (4 :

P < T > S < R < N > M

Comparisons is not possible.

Therefore, following the same reason, as for (2 this expression also does not hold good for the given conditions.

10.

Which symbol should come in place of question mark (?) in order to make P > L and S = N definitely false in the following expressions ?

P > B ? L = S = M ? N

Answer & Explanation

Answer : Option
C
Explanation :
Check for (1) :

P > B > L = S = M = N

Combining

P > L = S = N

So (1) makes it true.

Check for (2) :

P > B = L = S = M = N

Combining

P > L = S = N

One conditions S = N is still satified here.

Therefore (2) is not the right choice.

Check for (3) :

P > B > L = S = M < N

P > L = S < N

Thus > , < can be placed in order to make expression P > L and S = N definitely false.

Check for (4) :

We have check for = (between B and L) in

(2) and for < (between M and N) in (3).

So, we now only check

for > between B and L

and < between M and N

P > B > L = S = M < N

Combining

P > L = S < N

Thus P > L may be true.

Therefore (4) is not the right choice.
