Let the numbers be x and y.

x+y = 2xy

x(2y-1) = y

x = y/(2y-1). Here if y=1, x=1.

Thus the number = 11.

Let the numbers be x and y.

According to given question,

x+y = 2xy

y = 2xy-x

y = x(2y-1)

x = y/(2y-1).

if y=1, x=1

as 1 = 2(1)-1/1

1 = 2-1/1

1 = 1/1

1 = 1

This is the only condition which satisfy the LHS AND RHS.

Thus the number = 11.

I hope it will help u buddy.

Pls mark it as brainliest ans brother.

abhishekb740: Thanks
