Question

Q is a point on the line BD dividing the segment internally. AB, PQ and CD are drawn perpendicular to BD. If AB = a, PQ = b and CD = c, then

• A. $\frac{1}{a} + \frac{1}{b} = \frac{1}{c}$
• B. $\frac{1}{a} + \frac{1}{c} = \frac{1}{b}$
• C. $\frac{1}{a} - \frac{1}{b} = \frac{1}{c}$
• D. $\frac{1}{b} + \frac{1}{c} = \frac{1}{a}$

Answer 1

The Correct Option is B

The correct option is (B): $\frac{1}{a} + \frac{1}{c} = \frac{1}{b}$
