Q7) Correct Answer is 660 Explanation: Let the no. Of families be x. Families have 2/3 children=100%-(2%+8%+18%+27%) ==> 45% Now we know that 45% is 297 families. Finally, 45% of x is 297 -->45x/100=297 -->9x/20=297 -->x/20=297/9 -->x/20=33 -->x=33×20=660 Therefore, the total no. of families in that area is 660.
Question Number 5) 10:25, if the pebbles are subtracted from one urn, shouldn't it be added in the second urn as well? Like urn A should be A + 20 and urn B should be B - 20... Am I right? Please correct me...
if 20 pebbles are removed from B and added to A The numbers becomes interchanged i.e. B-20 becomes A and A+20 becomes B. Both of these gives same equation (B-A = 20)
Question no. 4, as dividing anything by 3/4 means multiplying it by 4/3, anything that is multiplied by 4/3 will be larger than itself multiplied by 3/4 as 4/3 is larger to multiply with, therefore we will subtract (m divided by 3/4) with (mx3/4) as m divided by 3/4 is a larger number than m multiplied by 3/4, therefore the answer will be 24 not -24, we can take M as 1 and you will find out the same logic applying.
In Q. No. 7, Why didn't we just simply add all the given persentage of the families i.e 55% of 100. Since, we assumed 100 families and then find the actual number of the family? P.S:- very informative and helpful contents, thank you for the videos sir
Here it's give rest of the families... It means that eliminating the 2% and 8% from total which gives 90% then the 18% and 27% are to be considered from 90 % of left over that is 45%(18%+27%) of 90% We can't simply add the percentages .. hope this helped

i got ypur point but what sir did is correct let me explain. when 20 pebbles from b were added to a they say their numbers got interchanged (that means a became b and b became a) ttherefor b-20 (THIS IS HOW many PEBBLES REAMINING AFTER REMOVING 20 PEBBLES THAT IS A BCzTHEY HAVE SAID AFTER REMOVING 20PEBS NUMBERS GOT INTERCHANGED) THETREFORE b-20=a (b-20=b here interchange b with a you ll get b-20=a) and the same logic to second case but in that case a became twice that of b thats it. i think that clears your confusion.
hello sir, i have a doubt on question number 5....after adding 20 pebbles from urn B to urn A, the urn A will be A+20. But U r not tell like that. why ?
The approach you used for que. 7 is confusing and doesn't make sense, i think there must be other approach. If anyone knows then please help me. Thank you! :)
Kindly check whether the ans for 5th question is ryt!! Bcoz I saw the ans was 50 and 70 respectively in another website and their explanation was correct...
The question in this video in easy ,but actual question is difficult.please solve difficult questions in the video and tell tricks to solve difficult questions.
In question 5th we have 2 equation and they add them but in question 2 we make 3 equation by multiply equation 1 with 4 and we subtract equation 3 with equation 2. Why we didn't add both equation 1 and 2 in question 2 as well.. please help, I am confused
great video so far...but i think there is one mistake, in question 5. the 1st equation should be.. a + 20 = y - 20 2nd equation will be... 2a - 20 = y + 10.
Sir in question 6 pebble one in first equation why u have not diducted 20 from B when they were shifted to be we have just written but in other equation u have effected both sides of the equation ! Could u plz recheck

Question number9 ----- aap kese m square--m--210=0 se m square -15m+14m-210=0 ye equation laye??? Plz kya formula boliye..... Exactly 15 and 14 kahan se laye???? Koi viewer ko pata he to kindly bataiye...
inhone factorise kiya.... 210 ko toroge to aapko 14 *15 milega....or B ka value -1 he use pane k liye -15+14 karne se mil jaiga...( Basically teacher ne factorization of quadratic equation perform kiya he)
Can question no. 7 be done this way, lets add all family percent (2+8+18+27) = 55% Now remaning 2 and 3 children =100-55 45 ℅ Now (2 and 3 children) = 297 Let total familes= x Now 45℅ of x = 297 X= 600
He takes that remain 90 families as 100%. Then 45% of 90 have (4 or 1 children ) So,55% of 90 have (2 or 3 children). Total 100%= 90 families. Hope you understand this,now.
Yes what about if we add 2%,8%,18%,27% we get 55% if we subtract from 100...45% of families have either 2 or 3 children 45%100=45 as we cross multiply we get 660as answer
Sir ur answer is question 7 is wrong If there are total 600families them families having 2or 3 children is 55% which means 55% of 600 i.e. 330 families. And in question it if given that 297families have 2or3childen So total families gonna be 297× (100/55) =540 😉

Q7) Correct Answer is 660
Explanation:
Let the no. Of families be x.
Families have 2/3 children=100%-(2%+8%+18%+27%) ==> 45%
Now we know that 45% is 297 families.
Finally, 45% of x is 297
-->45x/100=297
-->9x/20=297
-->x/20=297/9
-->x/20=33
-->x=33×20=660
Therefore, the total no. of families in that area is 660.
read the question properly amongst the 90% is given there
Question no.5 in which added 20 to a now a+20 and b-20
exactly a value will be modified to a+20.
Yes
yes that's right and the ans comes is 70 and 110
You can make the number 3 problem more easy, if you assume that the numbers are,
x-2, x-1, x, x+1 ,x+2 . Sum these numbers and it will be 5x=335.
Sir Actually for Q.5 A=70 and B=110 as equation 1. A-B =-40 and 2. 2A-B=30
for q 6...can we take whatever three digit number we want?
No.. actually A=50 , B=70 only.. Sir said correct

Question Number 5) 10:25, if the pebbles are subtracted from one urn, shouldn't it be added in the second urn as well? Like urn A should be A + 20 and urn B should be B - 20... Am I right? Please correct me...

if 20 pebbles are removed from B and added to A The numbers becomes interchanged i.e. B-20 becomes A and A+20 becomes B. Both of these gives same equation (B-A = 20)

This is my first video in ur channel your explanation is very good sir☺️
IN QUE 5, number of pebbles in B becomes twice, so right hand side should be multiplied by 2.
ya same doubt here
No
Yes I also think
You are right
Its "no.of pebbles in B are twice the number in A" so it will be 2A=B
For Sum 11)
We can take 'x' as no. Of girls and '50-x' remaining no. Of boys
So,
As per given data
5(50-x) + 7x = 280
250 -5x+7x=280
2x=30
X=15 girls
In question 5 ... The pebbles in B is 2 times the pebbles A... Then it will be 2(B+10) ... Can u explain how u have taken on the left side
its have a big solu if yu want then text me yur email i’ll send yu the solu
Same doubt. Plz answer

Thanks so much! You have been a huge help for my exam.
Very nicely taught, to everyone reading comments the ans for Q5. is A=10 B=30
Exactly
Your teaching really helped me a lott .. Thank you so much for the videos. Keep Going!!
q-5) the first equation is wrong ,if i move 20 pebles from B to A then A Will have 20 pebles more, B=A+40 is the correct equation
In qstn no 10..if we take A =TU and B=UT we will get A=27 B=72
Excellent explanation Sir. Thank you very much 🙏🙏🙏🙏🙏☺️☺️☺️
28:20 For Q10 , let's AB be the no. , B=A-45 (eqn 1) ,
A+B=9 (given)
A+A-45 = 9 (from eqn1)
2A = 45+9
A = 54÷2 = 27
or q 6...can we take whatever three dugut number we want?
quick sol of q7
2%+8%+18%+27%=55%
297 rests i.e 45% having two or three.
45%x=297
x=600
how 45% of x =297 become x=600,it comes 660. tell plz?

In question number 4 u cannot able to cancel 7m with 14 instead u have to find the difference between 14-12 by LCM and then it becomes 7M=2 .so m=2/7
5th question:
In 1st equation, why you didn't take
B-20 = A+ 20 ?????
And then in 2nd equation you did
A-10 = B+10
i got ypur point but what sir did is correct let me explain. when 20 pebbles from b were added to a they say their numbers got interchanged (that means a became b and b became a) ttherefor b-20 (THIS IS HOW many PEBBLES REAMINING AFTER REMOVING 20 PEBBLES THAT IS A BCzTHEY HAVE SAID AFTER REMOVING 20PEBS NUMBERS GOT INTERCHANGED)
THETREFORE b-20=a (b-20=b here interchange b with a you ll get b-20=a)
and the same logic to second case but in that case a became twice that of b thats it.

Can question no. 7 be done this way, lets add all family percent (2+8+18+27) = 55%
Now remaning 2 and 3 children =100-55
45 ℅
Now (2 and 3 children) = 297
Let total familes= x
Now
45℅ of x = 297
X= 600

same here
Did you understood how?
@@mayureshlavangare116 nope😂
He takes that remain 90 families as 100%.
Then 45% of 90 have (4 or 1 children )
So,55% of 90 have (2 or 3 children).
Total 100%= 90 families.
Hope you understand this,now.

@okbei9577 I have the same Querrey but when I read the q again I found that it's clearly mention in the Q that amongst the rest of the families
Make part 2 video for this number problems with some tricky questions
Sir ur answer is question 7 is wrong
If there are total 600families them families having 2or 3 children is 55% which means 55% of 600 i.e. 330 families.
And in question it if given that 297families have 2or3childen
So total families gonna be 297× (100/55) =540 😉
