Thank you so much for question and answer

[@vaishnavipatil7832]

We can simply do this.. Let, students age =S Teacher's age =T Average age of student and teacher= S+T/11(10students+1teacher) So, 15=S+T/11 165=S+T 165=7(15)+3(11)+T 165=138+T T=27

Q.No 3 (Easy way) Let Rohan age be 'x' years Meena = x-y Rohan = x Ajay = x+y given -> Meena + Ajay = 108 ==> (x-y) + (x+y) = 108 ==> 2x = 108 ==> x = 54 (Final answer)

[@adityaramekar74]

guys Q2 is correct because you have to assume 3 things: 1)past age(P-12 &Q -12) 2) present age(P&Q) 3) future age(after 12 years=P+12,Q+12)

[@saddamhussainshaik595]

In question no7 we need to consider the youngest also 6yrs ago he was born which means he is there so we need to count him as the 4 th member avg = sum /total no of members i.e avg=120/4= 30

[@harshadkrishna2203]

correct

[@tushar_kesharii]

yes , I things that will be the right answer ( 120/4 )

[@rejilreji8006]

Sir in the 10th question the avg age of 4 people was 19 and that was 4 years ago. When you calculated you just found the sum without considering the difference in age 4 years ago.

[@prasannapoola24]

For Q.2 I think answer is wrong because p,q is considered as present age. The answer might be p,q age is 24,16 respectively. present age of p=3x Present age of q=2x 3(2x-12)=(3x-12) 6x-36=3x-12 X=8 Therefore p age==3*x=3*8=24

[@siddharth.chandani]

Jo answer is wrong as according to the question after 12 years ratio of q to p is 2:3 and 28:36 != 2:3

[@reynewton5495]

Everything is easy, you just need to learn the basics and keep practicing.

8) m1+m2+m3+m4/4=19 m1+m2+m3+m4=76 (total age of all members is 76 yrs) 4 yrs back , 4members *4=16 yrs Total age =92 yrs .. After the birth of child m1+m2+m3+m4+m5/5=19 m1+m2+m3+m4+m5=95 92+m5=95 m5=3 yrs

[@donanath6002]

7. Total age of 4=(4*36)=144 yrs.. Without the youngest friend total age =(144-6) =138 yrs..this is the total of 3 friends.. Now avg of 3=(138/3)=46 yrs.. So at the time of birth the avg age was 46-6=40 yrs

[@miasanmia03]

👏

[@Happymind1331]

But...at the birth of youngest friend he exists and he is 0 yr and some days old....why we dont consider him?

[@MUSKAN_SHEIKH155]

*See How easy it was!!* I love that😅😂😂❤

[@nidahaq9787]

in q#7 avg o group has to be taken six year back , even though youngest ager was 0 we have to consider him in calculating average. ie [0+(A-6) +(B-6) +(C-0)] /4

[@rahul143goswami]

In 7th question eg if a student gets 0 in eng 10 in Hindi 20 in maths then avg will b 30 divided by 3 not 2 so even value is zero we need to consider in number of items so ans in 7 q will b 120/4

[@paspuloorinikhitha4340]

No here before 6 years that person not born so not include him. So no of persons only 3.

[@chaithravasista1622]

very nice video sir. Initially i was failing to understand the question itself..after watching this video it has helped me to get the nearest answer at least. Thank you for the video.

[@CareerRideOfficial]

Glad to know that, Chaithra. Keep practicing. That's the key to crack Aptitude test.

[@lhingsvlog7628]

Thankyou so much sir for sharing your knowledge especially for using English to explain🙏

[@designversed1]

In Q-7 "The average age of group...." why didn't we considered the youngest member as a part of the group before 6 years? we divided by 3 to find out answer instead of 4? Great Video Lecture btw.. ;)

[@rosemill2017]

Because we are considering the age of the three friends at the time of fourth one who was 0 years old

[@yashmakode7038]

@devansh your right

[@shashankkumar3415]

according to me the given solution is wrong we should divide by 4, even the age of youngest friend is 0 but he is still the part of the group.(if a batsman plays 10 matches and scores 0 in 1 match then also we include that match, I hope this analogy helps and i am correct with my solution).....do reply and correct me if I am wrong

[@Happymind1331]

​@@rosemill2017but that 0 year old kid exist so we should consider him.......consider cricket scenario....is batsman plays 4 matches so we get the average runs per match by dividing total runs by total matches even if he scores 0 in one match or any number of match 😅😅?plz clear my doubt

[@brosiscompany5547]

I am having amcat exam after 4 hours, thank you for your video

[@arunsuresh8547]

For qn 3) Let ages of Rohan , Ajay , Meena be R , A , M .. Rohan is younger to Ajay so their difference of ages A-R Rohan is elder to Meena so their difference of ages R-M A-R=R-M A+M-2R=0 Gn: A+M =108 Sub , 108-2R=0 R=54 yrs

[@Zara-hk2tw]

hmmm

[@rishabhjain7313]

Sir As 6 years ago the age of youngest friend is 0 years it doesn't mean that he doesn't exist. So the average age should be 30 years.i.e (120/4).

[@popisarkar802]

So according to you Averag age of that child is 30 year?

[@kedarnaik9296]

In question 7, the average cant be greater than 36 when we take it 6 years back. according to your solution you have divided by 3 and hence you got 40. Whereas you should have divided by 4. The answer then would be 120/4 = 30.

[@bharanisrikanth7102]

Avg of 4 friends, (A+B+C+D)/4=36 sum of 4 friends, (A+B+C+D) =36*4 =144 Assume youngest friend is D, and he was 6 years old, (A+B+C+6)=144 (A+B+C)=138 At the time of youngest friend birth, i.e 6yrs before, because D=6 Yrs old Sum of the A, B & C 6Yrs before (A+B+C)=138-6-6-6 =120yrs Avg of A, B & C =120/3 =40yrs

[@ranamanu86]

@@bharanisrikanth7102 why 120/3 not 120/4.if infant is born then y we are not considering him in av. i tell u this by example assume G father age is 60 and g.mother age is 40.then the av will be 50.if we add age of infant i.e. of 0 yrs then av will be different not 50. please clear this
