As mean is 50 so, 54-50=4 4*5=20 Last 3 nos 52-50=2 2*3=6 Both the numbers are more so add both i.e 20+6=26 Now 50-26=24 is 6th no. Did you get?

@sonam kurdekar pher to aapke hisaab se es qusn ka ans 69 hona chahiye instead of 57... Meanwhile koi 1 question to galat h chahe avg of 11 no. Wala ya avg of 9 no. Wala

57 is right answer as 18-12=+6 Then take opposite sign. 63-6=57
I have the same doubt.

agar koi no 2 bar liya gaya hai to always subtract hoga and agar koi no ek bar bhi Nahi liya Jaye to always add hoga

=50×9−(54×5+3×52) =450−(270+156)=450−426 = 24

50 wale question mai 6th average is not included in so sir first added both +20 and +6 and finally subtract ... and previous question mai 63 average wale it included in both with 60 and 65 so wha phle hi subtract.

please koi sir ka naam bata do
sir I have a doubt to slv this question ..... Q:-The average of 9 nos. is 30 . the average of first 5 nos. is 25 & that of the last 3 nos. is 35. what is the 6th no.???? answer:- 6th no.=30-10=20 hona chahiye na. because first avg. is 5 less to mantain krnge to +25 & 2nd me mantain krnge to -15 hoga Jo Avi v +10 jyada h to ise to 30 me se minus krnge ..... bt answer is 40... sir if I am wrong pls rply.

avg of 9 no is 30 ,(25 -30= -5 ) &(35-30=+5) so -5*5nos=-25 and +5*3 nos =15 therefore -25+15=-10 since in this case ( 12345)6(789), 6 is left so to maintain avg we always take opposite sign +10 ( above we get -10) so +10 +30 avg=40 ANS are you understand?

hey it can be done wid another trick dat sir told in type 1....avg of 9 nos is 30=270 first 5 avg is 25 so, 25*5=125 last three avg is 35 so,35*3=105...we need to find 6 no so 270-125-105 = 40 Ans.
HOMEWORK QUESTION : 1st four Avg is 4 And Last 4 is also 4 Total Average is 3 for 7 numbers. Answer : Given, 1st 4 Number Average is 4 which is +1 than the total average and last four is 4 which also +1 than the total average i.e., 4+4 = 8 ... So the 4th Number is 8 more than the total average 8+3 = 11 56 answer of homework question.

and what about 3 rd numer? it is 0 . I think we can choose it according to option bcoz we have 3rd and 4th number and their sum is 11 so we take any value of 3rd and 4th. but the sum of both number must be 11.
Seriously sir... Your tricks were awesome..... nd woh 3 star wali baat aajtk kissi ne nhi boli.... thank u ...upto infinity....
