last hint of the question is wrong (Question: 92162.1 )

= means it should be either greater nor equal then only = is =

Question:

DIRECTIONS: In the following questions, the symbols +, -, x, ÷ and = are used with the following meaning as illustrated below:


• ‘P + Q’ means ‘P is greater than Q’. 

• ‘P - Q’ means ‘P is greater than or equal to Q’.

• ‘P × Q’ means ‘P is equal to Q’.

• ‘P ÷ Q means ‘P is smaller than Q’.

• ‘P = Q means ‘P is either smaller than or equal to Q’.


Now in each of the following questions assuming the given statements to be true, find which of the conclusions I and II given below then is/are definitely true.

Statements:

S = F, K ÷ S, B × K, R + B


Conclusions:

I.  F + K

II. K ÷ R

Options:
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 Conclusion I and II are true
Solution:

Ans: (e)

According to question: 

S = F ⇒ S ≤ F ------(1) 

K ÷ S ⇒ K < S------(2) 

B × K ⇒ B = K-----(3) 

R + B ⇒ R > B ------(4)    

On combining the statements: 

R > B = K 

F ≥ S > K  

Conclusions: 

I.  F + K ⇒ F > K (True) 

II. K ÷ R ⇒ K < R (True) 

So, both the conclusions I and II are true.

Hi, you must know english grammar also to understand the reasoning...

After 'either' always 'or' comes..not nor...


and 'nor' comes after 'neither'...

‘P = Q means ‘P is either smaller than or equal to Q’.
so, = means < or =

Ans: (e)
According to question:
S = F ⇒ S ≤ F ------(1)
K ÷ S ⇒ K < S------(2)
B × K ⇒ B = K-----(3)
R + B ⇒ R > B ------(4)
On combining the statements:
R > B = K
F ≥ S > K
Conclusions:
I. F + K ⇒ F > K (True)
II. K ÷ R ⇒ K < R (True)
So, both the conclusions I and II are true.
