In the following questions, the symbols §, *, $, @ and © are used with the following meaning as illustrated below:
‘P $ Q’ means ‘P is neither smaller than nor greater than Q`.
‘P § Q’ means ‘P is not smaller than Q’.
‘P © Q’ means ‘P is either smaller than or equal to Q’.
‘P * Q’ means ‘P is smaller than Q’.
‘P @ Q’ means is neither smaller than nor equal to Q’.
Now in each of the following questions assuming the given statements to be true, find which of the two conclusions I and II given below them is/ are definitely true ?
Give answer:
a: if only Conclusion I is true.
b: if only Conclusion II is true.
c: if either Conclusion I or II is true.
d: if neither Conclusion I nor II is true,
e: if both Conclusions I and II are true.
Statements : T * K, K © M, M § D
Conclusions :
I. D * K
II. M @ T
statements with their explanations are:
T * K: T<K
K © M:{K}$$\leq$${M}
M § D:{D}$$\leq$${M}
two simplified equations are:
T<{K}$$\leq$${M} AND {D}$$\leq$${M}
conclusion I. D * K:D<K, which cannot be definitely inferred as there is no direct relation between the two
conclusion II. M @ T:{M}$$\geq$${T}, this can be directly inferred from the equation above.
since only conclusion 2 can be inferred and not 1 therefore the answer is option B
