The sum of two numbers is 25 and the product is 35. The sum of their reciprocals is:

Correct option is D

Given:
Sum of two numbers = 25
Product of two numbers = 35
Formula Used:
Sum of reciprocals = $$\frac1a +\frac 1b = \frac{a+b}{ab}$$​​
Solution:
Let the two numbers be 'a' and 'b'.
Given, a + b = 25 and ab = 35.
Sum of reciprocals = $$\frac{a+b}{ab} = \frac{25}{35} = \frac {5}{7}$$​
