In the following questions, the symbols * $ § © and % are used with the following meaning as illustrated below:
‘A § B’ means ‘A is neither greater than nor equal to B’.
‘A % B’ means ‘A is neither smaller than nor greater than B’.
‘A * B’ means ‘A is not greater than B’.
‘A $ B’ means ‘A is greater than B.
‘A © B’ means ‘A is either greater than or equal to B’.
Now in each of the following questions assuming the given statements to be true, find which of the two conclusions ! and II given below them is/ are definitely true ?
Give answer a: if only Conclusion I is true.
Give answer b: if only Conclusion II is true.
Give answer c: if either Conclusion 1 or II is true.
Give answer d: if neither Conclusion I nor II is true.
Give answer e: if both Conclusions I and 11 are true.
Statements :
B % T, T©M, M*D
Conclusions :
D©B M * B
statements and their meanings are as follows:
B % T:B=T
T©M:{T}$$\geq$${M}
M*D:{M}$$\leq$${D}
these can be simplified into set of two equations as: B>{T}$$\geq$${M} AND {D}$$\geq$${M}.
conclusion 1:D©B implies {D}$$\geq$${B}, cannot be inferred from the above equations
conclusion 2:M * B implies {M}$$\leq$${B} can be inferred from the above equations , hence is true.
since only conclusion 2 can be inferred from the above equations therefore answer is option B
