00:07:39And the number of sum is n into n plus 1 by 2.
00:07:43This is a direct trick for numbers to add.
00:07:46So, we have square and rectangle to count the trick.
00:07:49But here the rectangles are basically quadrilateral.
00:07:53So, if only rectangle, if we have to make it,
00:07:56we have to make total rectangle, square.
00:08:00Total rectangle, square.
00:08:04So, we have to make it all.
00:08:07Now, check this for yourself.
00:08:09Why do you need to tell me why you can do it?
00:08:11Now, this one has a reason for which side of the page is not going on.
00:08:15We will have to make it all the way possible to clean up.
00:08:20I will��� if I can do it every single day.
00:08:24I will like to make it all the way possible.
00:08:25Now, I remember this question's question.
00:08:28We have received questions in the comments section.
00:08:30I will have more questions in the comments section.
00:08:33All right, let's take a question and answer questions.
00:08:35here, you can't remember.
00:08:39Okay, this is the CGL 2022 question.
00:08:42CGL 2022 exam question.
00:08:46Okay,
00:08:48this question is the answer.
00:08:54How many quadrilateral are there in this picture?
00:08:58This picture is the quadrilateral.

00:14:13.
00:14:15.
00:14:19.
00:14:23.
00:14:25,
00:14:27.
00:14:28.
00:14:29.
00:14:31.
00:14:33.
00:14:35.
00:14:36.
00:14:37.
00:14:38.
00:14:412 the numbers 1 plus 2 plus 3 and multiply
00:14:482 the numbers to the numbers 1 plus 2 plus 3 plus 4 plus 5
00:14:53multiply
00:15:04Is there a total of 90 or 90 quadrilateral total is the exact same thing.
00:15:12This is a basic trick.
00:15:14The number of columns is multiplied by a number.
00:15:16This trick.
00:15:18Okay, for now, if I have to see the number of columns of columns of columns,
00:15:22I'll decrease the column of columns of columns.
00:15:23I'll reduce the number of columns of columns like this.
00:15:28I reduce the number of columns of columns.
00:15:30The number of columns of columns is in this figure.
00:15:32I will count the total rectangle quadrilateral. Sir, column number sum is 1 plus 2. Multiply, row number sum is 1 plus 2 plus 3 plus 4 plus 5, 1 plus 2 plus 3 plus 4 plus 5.
00:15:49I will count the total rectangle. If I count the total quadrilateral, I will count the total quadrilateral.
00:16:17This figure is how to count? Sir, here we go. Column number sum, multiply row number sum.
00:16:25Sir, column number sum, multiply row number sum.
00:16:28Now, column number sum is column number sum.
00:16:31If you have column number sum, then 1 into something, 1.
00:16:351 into something, something.
00:16:37So, here we go.
00:16:39If you have column number sum, multiply row number sum, 1 plus 2 plus 3 plus 4 plus 5.
00:16:49So, 1 into 15, how much?
00:16:511 into 15, how much? 15.
00:16:53So, here we go.
00:16:57Here we go.
00:16:58Here we go.
00:16:59Here we go.
00:17:0015.
00:17:016.
00:17:02Because 1 plus 2 plus 3.
00:17:03Here we go.
00:17:0415.
00:17:053.
00:17:06Because 1 plus 2.
00:17:07Here we go.
00:17:0915.
00:17:1015.
00:17:111.
00:17:12।
00:17:42and this is our final answer, because it is where it is, it is where it is, which is the basic concept. The basic approach we have learned is the rectangle count, which is the same approach.
00:17:54Now, let me ask you a question. This is the figure. I've asked you, total, and how do you answer this?
00:18:1610 चत्रबुज है अच्छा आप एक बात बहुत अच्छे से जानते हैं है ना कल मैंने आपको सिखाया था कि जब हम एक
00:18:23line इसमें draw करते हैं तो एक line कितने नई चत्रबुज देती है तीन चत्रबुज देती है उसके
00:18:29साथ दूसरी line draw करते तो 4 तीसरी करते तो 5 है ना number of lines number of rectangles को बढ़ाती चली आती है तो जैसे मैं यहां पर एक line
00:18:38खीचूंगा तो यह एक line कितने नई rectangle देगी यह बताओ यहां पर एक line कितने नई rectangle देगी सर एक देगी left में एक देगी right में देखो कितने
00:18:47rectangle बनेंगे हमारे एक तो बनेगा right में और एक बनेगा मेरा left में यह दो नई rectangle बनेंगे एक left में बनेगा
00:18:56एक right में कितने चत्रबुच नई बन गिया दो चत्रबुच मेरे नई बन गया दो चत्रबुच ठीके जीワ
00:19:02So, if I have one line here, if I only have one line here, if I only have one line, then this line will be two.
00:19:12And this line will be two rectangles.
00:19:18So, if I have one line here, if I have two rectangles, then this line will be two.
00:19:38If I have one line here, I will be two.
00:19:50So, this line will be three.
00:19:53Right hand side will be three.
00:19:55One will be this, and one will be this.
00:19:59Two will be this, and one will be this.
00:20:01Two will be this, and one will be left hand side.
00:20:05Two will be right hand side.
00:20:07One will be left hand side.
00:20:09So, three will be this.
00:20:11Okay?
00:20:12Yes.
00:20:13And finally, if I have one line here, this will be two.
00:20:20So, this will be my new rectangle.
00:20:22Now count.
00:20:23Total will be this rectangle.
00:20:2510 will be this.
00:20:2610 will be this.
00:20:272 will be this.
00:20:282 will be this.
00:20:292 will be this.
00:20:302 will be this.
00:20:312 will be this.
00:20:322 will be this.
00:20:335 will be this.
00:20:3410 and 3.
00:20:353.
00:20:3616.
00:20:3710.
00:20:3810.
00:20:3910.
00:20:4010.
00:20:4113.
00:20:4210 again.
00:20:4420.
00:20:4513.

00:21:02This is a single-back between this, but with this, the count of this, we'll get to this.
00:21:083 count, 2 count?
00:21:12Basic was 10, 2, 4, 6, 8, 10, or 13.
00:21:1513 and 10, 13 and 10, 13 and 10, 23's the right answer.
00:21:21So you can create a tiny line with this concept,
00:21:263rd box
00:21:293rd box
00:21:323rd box
00:21:341 line
00:21:342
00:21:352
00:21:353
00:21:373
00:21:374
00:21:515
00:21:515
00:21:516
00:21:536
00:21:557

00:22:48तो 1, 2, 3, 4, 5, ये 5 ओ नमबर आपस में add कर दो, पांचिंग 30 बता दो 15, तो यहाँ पर 15 है, तो यहाँ पर 15 है, प्लस extra count कर लो, क्योंकि single column या single row में total चत्रबुज कैसे निकालते हैं, ये जो numbers है न, इनी numbers को आपस में add कर दो, इनी numbers को आपस में add कर दो, इनी numbers को आपस में add क
00:23:18single row या single column में निकालने के लिए इनी numbers को आपस में add कर दो,
