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,
Whichof the following is a possible chain of molecules ?
Which of the followings is NOT possible chain of molecules ?
The chain W W T Y Z X can be changed into another chain by carrying out any one of the following EXCEPT
Which of the following is not a chain but could be turned into a chain by changing the order of the molecules ?
Which of the following sequences can be converted into a chain by adding Z and rearranging the molecules ?
I. X Y X T
II. W T T Z
III. X X Y W
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 :
Statements: B @ V,K © C, C © B
Conclusions:
I. V @ C
II. B @ K
Statements : K @ T, S = K, T © R
Conclusions :
I.S @ R
II. T = R
Statements : U = M, P @ U, M @ B
Conclusion :
I. P = B
II. P @ B
Statements: L @ N, J © P, P @ L
Conclusion:
I. J = L
II. P = N
Statements:H @ G, D @ E, H = E
Conclusion:
I. D @ H
II. G @ D
