Easy way to find the answer of qn no 12 :- Total run used in increases the avg = 17*3=51 So the remaining runs used for previous avg i.e = 87-51=36 If previous avg 36 then current avg = 36+3=39 I think it's useful 😉...
Q15 50:45 Ans:- sum of 7 technician=7*12000=84000 Let assume rest workers are x Sum of all = (7+x)* 8000= 56000+8000x Sum of rest technician 6000x 56000+8000x=84000+6000x 8000x-6000x=84000-56000 2000x=28000 X=28000/2000 X=14 Therefore total number of workers in the workshop 7+14=21

Can you explain 43:50 Q no.9 if we assume that the sum of last three numbers is (x) And first number is (1/4*x) Then, 240 = 1/4*x + x 240 = 5x/4 X= 192 Please explain it

At 43 min, in que 9, if we assume the sum of 3 nos is x Then 1st no will be x/4 So, x+x/4=240 Or, 5x/4=240 Or, x=192 Can anyone tell how this relation of wrong? (X+X/4=240)
You have assumed X as the sum of last three observations ..and x = 192 now subtract the sum of last three observations that is x from the total sum , you will get T1=240-x T1=240-192 T1=48

Q15 50:45
Ans:-
sum of 7 technician=7*12000=84000
Let assume rest workers are x
Sum of all = (7+x)* 8000= 56000+8000x
Sum of rest technician 6000x
56000+8000x=84000+6000x
8000x-6000x=84000-56000
2000x=28000
X=28000/2000
X=14
Therefore total number of workers in the workshop
7+14=21
What's your age?
Bache huye sramik ka average
6000(X-7 )
X= 7
7 +7 = 14 aara mera
THANKYOU SO MUCH FOR THIS MANY LIKES. VERY MUCH APPRECIATED😄
12)
Let the avg be X, so avg of 16 innings is X-3
Total score after 16th innings - 16*(X-3)
Avg of 17th innings-
16* (X-3)+ 87= 17X
X = 87-48= 39
13) 32+4*11= 76
14) extra weight= 8*2.5= 20
Weight of new person = 65+20= 85
15) avg- 8000 let total no. Be x
Sum= 8000x
12000*7+6000(x-7)=8000x
42+3x-21=4x
X=21

Great explanation with visualisation. Thank you sir. I used to cram the formula for Q10). Today I understood the concept.
At 43 min, in que 9,
if we assume the sum of 3 nos is x
Then 1st no will be x/4
So, x+x/4=240
Or, 5x/4=240
Or, x=192
Can anyone tell how this relation of wrong? (X+X/4=240)
You have assumed X as the sum of last three observations ..and x = 192 now subtract the sum of last three observations that is x from the total sum , you will get T1=240-x
T1=240-192
T1=48
1st no. Is x/4 so 192/4 = 48
No one can explain things like you
