Question

The sum of two numbers is 15. If the sum of their reciprocals is 3/10, find the two numbers.​

Answer 1

Answer:

5 , 10

Step-by-step explanation:

Let no be x,y

x+y=15

x=15-y

1/x+1/y = 3/10

= 1/(15-y) + 1/y = 3/10

= 15/(15y - y²)=3/10

= 150 = 45 y - 3 y²

= y² - 15 y + 50 = 0

= y² - 10 y - 5 y - 50 = 0

= y (y-10) - 5 (y-10) = 0

y = 10

x = 5

2 no are 5 and 10 .
