#### Mathematical operation and symbol notation

Direction: In the following information question, the symbol #, %, @, S and © are used with the following meaning as illustrated below:
'P # Q' means 'P is smallest than Q'.
'P % Q' means 'P is not greater Q'.
'P @ Q' means 'P is neither smallest than nor equal to Q'.
'P S Q' means 'P is neither greater than nor equal to Q'.
'P © Q' means 'P is neither smallest than greater nor greater than Q'.
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.

1. Statements:
R # T, T © M, M @ D
Conclusions:
I. D S T II. R # M
1. if only conclusion I is true
2. if only conclusion II is true
3. if either conclusion I or conclusion II is true
4. if neither conclusion I nor conclusion II is true
5. if both conclusion I and II are true
##### Correct Option: E

R ≥ T ...(i) T = M ...(ii) M > D ...(iii)
Combining these we get R ≥ T = M > D.
Hence D > T and I follows.
Also R J≥ T and II follows.
