The sum and product of two numbers are 12 and 35 respectively. The sum of their reciprocals will be :
A. $$\frac{12}{35}$$
B. $$\frac{1}{35}$$
C. $$\frac{35}{8}$$
D. $$\frac{7}{32}$$
Answer: Option A
Solution (By Examveda Team)
Let the numbers be x and yThen,
$$\eqalign{ & x + y = 12\,\, \& \,\, xy = 35 \cr & \therefore \frac{1}{x} + \frac{1}{y} = \frac{{x + y}}{{xy}} = \frac{{12}}{{35}} \cr} $$
