This "trick" is merely a basic algebraic identity rebranded to exploit the demand for exam shortcuts. It prioritizes rote memorization over the fundamental logic that any student should already grasp.

Number system 2 digit no. Trick 🔥 #infinitesimalAdded:
This question of number system is very poisonous. But the approach I am going to give you is even more pro level poison than that, brother. Ok? So what do you call a two digit number? For example, suppose there are x and y, then how do you write it? You write 10x + y.
Ok? And this is called the unit digit and this is called the 10s place digit. Isn't it?
I'm being told that 10x + y is your k times x + y. This is a very good thing. Ok? So I asked what is it? Please, if you read it carefully, it will be done. The number formed by interchanging the digits is the sum of times the sum of the digits multiplied by something that if I interchange them, this number is formed by interchanging them.
How many times is this number the sum of the digits?
So let's say n times. This is what is being asked, the value of n is being asked. Now if we solve this brother, we will keep solving it.
We do it in such a way that you either add or subtract.
You do whatever you feel like doing. Ok? But if I go to contract then there will be trouble brother. If I add it, then see what a great thing it will be.
If I add both of them, you will see that 10x and this x together will become 11x and this y and 10y together will also become 11y. So let's take 11 common ones. This will become x + y.
Why did you do it? I hope you understand because I see x + y here. If I even this side out, I take x + y as common.
So my brother will be left with k + n. Ok? Look brother, look at the view. This got cancelled. You had to remove n.
What will be the value of n? 11 - k will become. I will quickly mark option number C and tell you how you liked it? If you want such sessions, if you want such questions to be touched upon, then brother, subscribe to the channel. Turn on the notification bell because I am brother
