Answer:

10/17

Step-by-step explanation:

hey buddy here is ur answer

=========================

Let the fraction be (x/y).

(i) 3 is added to numerator and 4 is subtracted from denominator, it is = 1.

⇒ (x + 3)/(y - 4) = 1

⇒ x + 3 = y - 4

⇒ x - y = -7

(ii) 1 is subtracted from numerator and 1 is added to denominator, it is = 1/2.

⇒ (x - 1)/(y + 1) = 1/2

⇒ 2(x - 1) = y + 1

⇒ 2x - 2 = y + 1

⇒ 2x - y = 3

On solving (i) & (ii), we get

⇒ x - y = -7

⇒ 2x - y = 3

   -------------------

    -x = -10

     x = 10.

Substitute x = 10 in (ii), we get

⇒ 2x - y = 3

⇒ 20 - y = 3

⇒ y = 17.

Therefore, the fraction is (10/17).

Hope it helps!
