Answer:
Let the number be x.
x-20 = 69/x
Cross-multiplying,
x(x-20)= 69
x^2–20x-69=0
(x-23)(x+3)=0
Thus, x= 23 or -3.

Question:
- The sum of 2 numbers is 36 and their product is 248. What will be the sum of their reciprocals?
Answer:
- The sum of their reciprocals is 9/26
Step-by-Step Explanation:
Given:
- The sum of two numbers is 36.
- And their product is 248.
To Find:
- The sum of their reciprocals?
Solution:
Let us assume:
- One number be x.
- Another number be y.
Now,
We have:
- Sum of numbers = x+y = 36
- Product of numbers = xy = 248
Sum of their reciprocals:
➻ 1/x + 1/y
➻ y + x/xy
Putting the values;
➻ 36/248
➻ 9/62
Hence, the sum of their reciprocals is 9/26.
