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 QP + Q = a
PQ = b
⇒ $$\frac{{1}}{{P}}$$ + $$\frac{{1}}{{Q}}$$
⇒ $$\frac{{Q + P}}{{PQ}}$$
⇒ $$\frac{{a}}{{b}}$$
