Explanation

Let the required two number be X and Y.

According to question

X+Y =40…………………………(i)

And the difference of two number is 4

X-Y=4……………………………(ii)

On solving both equation

Add equation (i) and (ii)

2X=44

So X= 44/2=22.

And put the value of X in equation (i)

We get

Y=22–4=18

So Y = 18.

Hence ratio of resultant number is

22/18=11:9.
