Answer 2

Answer

Numbers are 10 and 5

Step-by-step explanation:

Let us assume two numbers as x,y.

x + y =  15 (given)

1/x + 1/y = 3/10 (given)

By solving the 2nd equation

(x + y)/xy = 3/10

1/xy = 3/150

xy  = 50

y = 15 - x

Substituting in 2nd equation

15x - x² = 50

x² - 15x + 50 = 0

By solving the quadratic equation

x gets two values 10 , 5

So the numbers are 10,5
