Let the no be =x other no be =y According to question x+y=15⇒Y=15-x 1/X+1/Y=3/10 1/x+1/15-x=3/10 taking LCM 15-X+X =3 (15-X) X 10 150=45X-3X^2 3x^2-45x+150=0 x^2-15x+50=0 x^2 -10x-5x+50=0 x(x-10) -5(x-5)=0 (x-5) (x-10)=0 x=5 ,x=10

Let the number be x and second number be y

so given x + y = 15 and

⇒

⇒ {x + y = 15}

⇒

⇒

⇒ { x + y = 15 ⇒ y = 15 - x }

⇒

⇒

⇒

⇒

⇒

so x = 5 or 10

so when x = 10 then y = 15 - 10 = 5 so x = 10 , y = 5

and when x = 5 then y = 15 - 5 = 10 so x = 5 , y = 10
