QUESTION
Rewrite the following statement without using conditional –
(Hint : p → q ≡ ∼ p ∨ q)
If demand falls, then price does not increase.
SOLUTION
Let p : demand falls.
q : Price does not increase.
The given statement is p → q.
But p → q ≡ ~ p ∨ q.
∴ The given statement can be written as ‘Demand does not fall or price does not increase’.
