Question

find those numbers yaar

Answer 1

let those two numbers are x and x+2
so by ques,

1/x + 1/(x+2) = 12/35

$\frac{2x + 2}{x(x + 2)} = \frac{12}{35}$
CLEARLY, x= 5
so, both numbers are 5 and 7.

Answer 2

Let Numbers be x and (x+2)

We are given,

1/x + 1/(x+2) = 12/35

Hence,  (x+2+x)/x(x+2) = 12/35

         (2x+2)/(x^2+2x) = 12/35

       Hence, (x+1)/(x^2 + 2x) = 6/35

= 35x + 35 = 6x^2 + 12x

6x^2 -23x - 35 = 0

Solving Above Equation,

x = 5 or x = -7/6

Since, x is a Natural No. x = 5

Hence, Numbers are 5 and 7
