Hmmm......

Then, you must be thinking of 19.






Explanation:

Let you numher be x

now
according to question

multiply it by 8 and it becomes 8×x = 8x

Now add 22
so it becomes
8x + 22

now as told in the question take the same number again i.e x for one more time.

multiply it by 6
and you'll get 6x
and after adding 60 you'll get 6x + 60

Now again according to question
8x+ 22 and 6x+60 are same number therefore they must be equal,

8x+22 = 6x+60

Do a little azebra

8x -6x = 60 -22
2x = 38
x = 19.

and Tada, your number is here.
