[00:13:30]Left 16th question. 16th question is 16th towards left. from left he is on 16th and 35th from the right and right 35th moan 35th moan right Right.

[00:14:12]This is 51. 51 - 1 is 50. 50 - 1 is 50.

[00:14:23]1 2 3 4 5 6 I suggest that is a very process.

[00:14:47]number left position plus right position minus of one. This will be our This will be our equal This will be our uh total number of total number of students. Total number of boys in the row.

[00:15:08]Next.

[00:16:30]Say in a row of boys 6 in a row of 65 boys, Sumit rank Sumit rank Sumit ranked this 42 from the left hand in a in a in a row of 65 boys. Sumit ranks 42nd.

[00:16:53]Sumit ranks Sumit rank 42nd ranks 42nd from the left hand. Right.

[00:17:07]Find the find rank from the right.

[00:17:18]So fortal is equal to left position plus of right position minus of one direction is facing towards north direction. Sumit is facing Sumit is facing north direction. Sumit is facing north direction.

[00:17:47]Sumit is facing north direction.

[00:17:51]Sumit is facing north direction. Okay.

[00:17:54]Total 65 square from the left hand. 42.

[00:18:06]So 42 from the left 42 right 65us of 42 + 1 is equal to right position 66 6 - 24 6 - 2 is 4 6 - Four is 24. Right position rank 24.

[00:18:39]Option number D for Dangistic is the right answer. Very good.

[00:18:45]Very good.

[00:18:52]Great. Lovely.

[00:19:04]Total number of people is equal to left position plus right position left position plus right position minus of one or else right position plus left position minus of one. The same thing applies on top and bottom also.

[00:23:05]In a row of 83 students, Rohit rank rank is for 37 from the right.

[00:23:12]Then find Rohit rank from the left position. DP grammatical correctal number of students number of students number 83 correctal number 83 rank is 37 from the right hand. So total is equal to left position minus of sorry plus of right position minus of one. Total is equal to left position plus right position minus of one position. Correct.

[00:24:11]Rohit rank is 37 from the right end.

[00:24:14]Then find rank from the left.

[00:24:18]Total done.

[00:24:23]Very good.

[00:24:28]So 83 83 total number of boys 83 is 37 from the right position 37 left 83us of 37 plus of 1= left position. So 84 84 4 - 3 4 - 7 7 - 3 is four. So 47 will be the right answer. That is option number C. C4 C form C for is the right answer.

[00:25:29]Total is equal to left position plus right position.

[00:25:38]Left position plus of right position minus of one.

[00:25:44]Left total plus of one minus of right position right total minus of one total minus of one minus of left position plus of one minus of left position.

[00:26:05]So for the same thing right bottom plus topus onetomot Minus of topus bottom of bottom.

[00:26:59]Clear.

[00:27:08]Yeah. Question.

[00:27:14]Yeah.

[00:27:57]32.

[00:27:59]Very good. Very good. This one Rohan's ranked seventh from the top position and 26th from the bottom position in the class.

[00:28:10]How many students are there in the class? So total total is equal to top position plus of bottom position minus one.

[00:28:22]How many students are there in the class?

[00:28:29]Total is equal to T total is equal to T total is equal to G seven from the top seven from the top this bottom 26 minus of 1.

[00:28:48]So this becomes 6 + 7 is 13 uh 13 33 33 minus of 1 is 32 correct 32 I said yes 32 option number B4 B4 district is the right Rohan ranked seven from the top 26 ranked seventh from the top It will be my top.

[00:29:41]So first, second, third, fourth, fifth, sixth, seven.

[00:30:01]bottom 26.

[00:30:04]So 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 20 19 20 1 2 3 4 5 6. So 26 bottom 26 comparison Rohan 26 28 29 30 31 32tal formula Yeah. Moving on to the next question.

[00:31:29]human.

[00:31:40][clears throat] So very easy question 27 total class of 40 rank 14 from the top.

[00:32:51]14 minus of total plus of 1 minus of top position.

[00:33:08]So total given 40 41 total 41 minus of top position 14 this is seven option number C4.

[00:33:29]Okay for very good. So this is the correct the C4. So I do say yeah.

[00:34:13]Total 40s.

[00:34:21]Huh? Total 40. Total 401.

[00:34:34]So in a class of 68 student rank hers rank is 27 from the bottom. Find the rank of H from the top. So total total is equal to top position plus of bottom position minus of one. So total 68 top from the top 27 68 minus of 27 plus of 1 = x.

[00:35:17]So 69 42 42 that is option number C 42 is the right answer 42 position from the top position 42 rank clear.

[00:35:47]Yeah.

[00:35:52]Yeah.

[00:35:56]42 42. Okay. Very good. Keep it up.

[00:36:56]Yeah. Answer.

[00:37:08]You want answer?

[00:37:13]29 in a row. Sh is 16 from the front and 21st from the back.

[00:37:32]and 21st from the back.

[00:37:40]16th from front. from front and 21st and 21st from back. 21st 37 37 minus of 1 36. The total number of students level 36. How many more people should be included in the row so that the total number of people becomes become 65.

[00:38:18]How many people should be included in the row? 365us 36 29.

[00:38:31]Option number Balot is equal to Total is equal to front position front position plus of bottom position minus of one formula for a front position So one andal 36 36US 36L 29 correct answer that is option number B for Take P become 30 minus 29.

[00:39:45]Yeah.

[00:39:59]Yeah.

[00:41:08]I answer [snorts] in a row of boys. A is 14 from the left.

[00:41:38]Again, a 14 by default noting by default.

[00:42:09]Not facing 14.

[00:42:29]This is the left position and this is the right position.

[00:42:35]and B is 19 from the right. So B 19 clear. So 19th B 19 from the right hand C is 22 from the left hand. C is 22 from the left hand. Left hand C is 22. So, 22 C 22 C 22.

[00:43:49]C 22 from the left hand and D is 35th from the left hand. Left. Left hand.

[00:44:26]D is D is 35th from the left.

[00:44:36]D35 D3 14.

[00:44:57]If C is 49 from the right, C 49 from the right.

[00:45:04]value 49 C is 49 from the right. How many total number of boys in the row? How many total number of boys in the row? So that is 14th from left hand side 22nd from left hand side.

[00:45:41]Sorry to say 19 rank 19th from right hand side 14th B rank 19 C rank say 22nd 22nd from left hand side C rank say 49th 49th from right hand side from right hand side. D rank D rank 35th from left hand side.

[00:46:18]Total number is equal to left position plus right minus one of one position plus right?

[00:46:44]So, right 49 of 71 minus of 1 is equal to 70. That is option number C. C for only com because only He also part of the total number of boys.

[00:48:02]He also part of number of boys.

[00:48:14]Very good.

[00:48:47]Question sir, please.

[00:49:24]In a row of boys, A is 13 from the left.

[00:49:29]Row of A is 13 from the left.

[00:49:35]So A 13th from the left. So 13th from left and D is 17th from the right. D is 17th from the 17th from the right. If A is 11th from the right end. If A is 11th from the right end.

[00:49:54]11 from the right.

[00:49:58]A 13 from the left. A line.

[00:50:14]11.

[00:50:19]What is the position of the left?

[00:50:22]Position of the left number of question.

[00:50:46]Total number of students number of sorrytal number of students number of boys Left total number of right position minus one correct.

[00:51:25]So left right.

[00:51:38]So using a to using a to me using using a to me total number of student because only a to my right position or left position. So using a 13 plus of 11us of 1 24 24 minus of 1 23 23 23 is the total 23 we come back to the formula total is equal to left position plus of right position minus oftus 23us of 17 plus of 1= left position 24 24 minus of 17 24 minus of 17 to 7 option number B so left position will be left position will be seven left position will be seven option number D clear seven Rahul Singh Very good. Okay.

[00:53:25]Okay.

[00:53:55]So in a row of boys A is 14 from the left. So this is our left position by default. So C rank Ds from left 22. C rank to my DS 49. D rank from left 3 is 19.

[00:54:27]Right.

[00:54:32]Left minus one right.

[00:54:49]So using C using number of boys from the Left hand this is also your homework question.

[00:55:53]Okay.

[00:55:55]Yeah.
