In the following questions, the symbol $$\delta$$, %, *, $ and © are used with the following meaning as illustrated below.
‘P % Q’ means ‘P is not smaller than Q’.
‘P * Q’ means ‘P is neither greater than nor equal to Q’.
‘P $$\delta$$ Q’ means ‘P is neither smaller than nor equal to Q’
‘P $ Q’ means ‘P is neither greater than nor smaller than Q’.
‘P © Q’ means ‘P is not greater than Q’.
Now 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
Statements: W © B, N $$\delta$$ B, N © F
Conclusions: I. F $$\delta$$ B
II. W * N
W © B which means W is smaller than or equal to B
N $$\delta$$ B which means N is greater than B
N © F which means N is smaller than or equal to F.
We can conclude that,
F is greater than B as B is smaller than N which is smaller than or equal to F.
W is smaller than N as W is smaller than B which is smaller than N.
Option E is correct.
