If sum of two numbers be a and their product be b, then the sum of their reciprocals is :

A. $$\frac{{1}}{{b}}$$ + $$\frac{{1}}{{b}}$$

B. $$\frac{{b}}{{a}}$$

C. $$\frac{{a}}{{b}}$$

D. $$\frac{{1}}{{ab}}$$

Answer: Option C

Solution(By Examveda Team)

Let the two number are P and Q
P + Q = a
PQ = b
⇒ $$\frac{{1}}{{P}}$$ + $$\frac{{1}}{{Q}}$$
⇒ $$\frac{{Q + P}}{{PQ}}$$
⇒ $$\frac{{a}}{{b}}$$
