Question 146

# Statements:H@K, K % D, D \$ B Conclusions:I.H @ B II.B @ K

Solution

The given statement can be written as $$H\leq K \geq D = B$$

The conclusions can be written as (i) $$H \leq B$$ (ii) $$B \leq K$$

From the statememnt , it is clear that no relation can be established between H and B. Hence, conclusion (i) is false.

We can see that conclusion (ii) is true.

Hence, option B is the right answer.
