In the following questions, the symbols *, §, %, @ and © used with the following meaning as illustrated below
‘P % Q’ means ‘P is not smaller than Q’.
‘P © Q’ means ‘P is neither smaller than nor equal to Q’.
‘P * Q’ means ‘P is neither great er than nor equal to Q’.
‘P § Q’ means ‘P is not greater than Q’.
‘P @ Q’ means ‘P is neither greater than nor smaller than Q’.
Now In each of the following questions assuming the given statements to he true.
find which of the three conclusions I, II and Ill given below them is/are definitely

Question 235

# Statement :W © T, T § N, N % DConclusions :I. D * TII. W © NIII. D @ T

Solution

statements with their meanings are as follows:
T § N:{T}$$\leq$${N}
N % D:{N}$$\geq$${D}

a simplified equation can be: {D}$$\leq$${N}$$\leq$${T}<W

conclusion I. D * T: implies D<T, cannot be said definitely because of the inequaity sign
conclusion II. W © N:implies W>N, true and can be inferred from the equations.
conclusion III. D @ T:implies D=T, cannot be said definitely because of the inequaity sign.
since only conclusion 2 follows therefore the answer is option C.
