Please give me correct answer​

Answer 1

Answer:

Let the required number be

y

x

Since denominator of the number is greater than its numerator by 3.

∴y=x+3.....(1)

Also,

y+2

x−3

=

5

1

5(x−3)=y+2

5x−15=(x+3)+2

5x−15=x+5

5x−x=15+5

⇒x=

4

20

=5

Substituting the value of x in equation (1), we have

y=5+3=8

Therefore,

Required no. =

8

5
