Solution

Q.
In the given figure, D is the mid-point of BC , then the value of $\frac{\cot y}{\cot x} i s$

1 2

2 1/2

3 1/3

4 1/4

Ans.
(2)

$F r o m t h e g i v e n f i g u r e \frac{\cot y}{\cot x} = \frac{A C}{B C} \div \frac{A C}{C D} = \frac{A C}{B C} \times \frac{C D}{A C} = \frac{C D}{B C} = \frac{C D}{2 C D} = \frac{1}{2} (U s i n g c o t θ = \frac{b}{p})$
