A researcher studying organic compounds has found that five different molecules. T, W, X, Y and Z form chains according to the following rules :
A chain consists of three or more molecules, though the molecules in the chain are not necessarily different.
T is never found on either end of a chain.

If W appears in a chain, it appears more than once.
X is never found next to y in a chain.
W is never found on the end of a chain
unless Z is found somewhere in the chain.
If Y appears in a chain, Z appears also,

Question 111

Whichof the following is a possible chain of molecules ?

Video Solution

Question 112

Video Solution

Question 113

Video Solution

Question 114

Which of the following is not a chain but could be turned into a chain by changing the order of the molecules ?

Video Solution

Question 115

Which of the following sequences can be converted into a chain by adding Z and rearranging the molecules ?

II. W T T Z
III. X X Y W

Video Solution

Instructions

In the following questions the symbols @, @, =, © and © are used with the following meaning :

P @ Q means P is greater than Q.

p @ Q means P is either greater than or equal to Q.

P = Q means is equal to Q.

P © Q means P is smaller than Q.

P © Q means P is either smaller than or equal to Q.

For each questions you have to assume given statements to be true and then decide which of the two given conclusions is / are definitely true. Give answer :

Question 116

Statements: B @ V,K © C, C © B
Conclusions:
I. V @ C
II. B @ K

Video Solution

Solution

B>V, K<C, C<B

1. We know that both V and C are less than B. But we don't have any specific relation between V and C.

2. We know, B>C>K, hence B>K. Hence, true.

Question 117

Statements : K @ T, S = K, T © R
Conclusions :
I.S @ R
II. T = R

Video Solution

Solution

K>T, S=K, T<R or T=R

1. We can conclude S>T. However, both S and R can be greater than T (or R=T), and hence, we cannot say that this conclusion is true.

2. This, again, is not certain.

Question 118

Statements : U = M, P @ U, M @ B
Conclusion :
I. P = B
II. P @ B

Video Solution

Solution

U=M, P>U or P=U, M>B or M=B

from the given information, there are two possibilities as for both P/U and M/B, there are two cases.

Either P=B or P>B.

Question 119

Video Solution

Solution

L>N or L=N, J<P or J=P, P>L or P=L

1. Since there are two cases of P and L, we cannot say that J=L.

2. Same logic as 1.

Question 120

Statements:H @ G, D @ E, H = E
Conclusion:
I. D @ H
II. G @ D

Video Solution

Solution

H>G or H=G, D>E, H=E

1. Since D>E=H, hence D>H.

2. G>E or G=E, and D>E, we can say that D>G.
