Another solution:
Original number minus the sum if its digits:
18 - (1+8) = 9
12 - (1+2) = 9

[@user-ke4te5wt7s]

Super

[@debasisrong5988]

1+2=(3)² =9 sir ji apne aise kiya answer ?

[@comictv7730]

Excellent

[@ANJUKUMARI-mf6wq]

1+2=9 how is this possible?

[@karthikcreationofficialak9355]

Awesome ❤

[@Naveenkumar-rc8zt]

18^2 = 324 , 3+2+4 =9 and 12^2 = 144, 1+4+4=9

[@LalitBadhautiya3236]

18-(1+8=9)18-9=9❤❤
12-(1+2=3)12-3=9😊😊😊

[@emh1164]

🎉

[@BerleyGaming]

Wow Thanks for the simple trick, my brain was not braining 😅

[@harmangill8328]

Thanku ❤mere kooo tooh apke comment syy simple samj aya 😅

[@ASHARANI-or5wr]

Yh dhakka krk bnayi h aapne 😅😅

[@ASHARANI-or5wr]

6×3=18
3×3=9
4×3=12
L. C. M = 3×3×3 = 9 answer

[@dilli418]

18x3 54 5+4=9
12x3 36 3+6=9

[@badalnayak834]

3 not is question

[@YRON.GAMING]

36 bro

[@ayushkumarjha5624]

Not logical ..

[@tkk6450]

I would take 9 anyway because its smaller than 12 😅

[@janebrown7231]

Yes I agree - it was pretty obvious!

[@harikrishnang2869]

Absolutely 😂

[@vallakonda_rohith.]

Logic hai!😁

[@gamerzzone6986]

😅

[@somashreedas9184]

True

[@NaveenKumar-ro9zw]

These type of questions are illogical. How is related to the work ?

[@ajyap2328]

well bro, questions like that will test your cognitive flexibility, your ability to recognize pattern and most importantly, the methods you formulate to get the answers. Works are not just about physical attributes, but they also require mental adaptability as wellm

[@AdarshSharma-cr8bb]

They should do something else to test . These Q are illogical fr like it can have many relations

[@aneesharyan3910]

Exactly illogical questions to test your logical reasoning

[@BeHumanFirst-]

If that's called ability to recognize pattern than it means the candidate must think only according to how examiner wants , when this types of questions come students try everything to solve it but at the end what happen all the logic becomes illogical, like all your hard work gets in dust just becoz you can't think according to the examiner at that particular time🥴@ajyap2328

[@RiyaPaliwal-qm6nr]

Ans 9 h
18 ka square 324=3+2+4=9
Similar
12 ka square 144=1+4+4=9

[@srskannada1549]

supr❤

[@viralngayon4554]

18:9=12:x
18.x=9.12
18x=108(18 divide both side )
X=6

[@amnztube]

Reasoning or maths alag alag hota hain

[@Manu_HR_31]

Bohot achi tricks hai sir ji 🙏

[@GuinnessAndMathGuy]

😌

[@Ren110]

4:39 I can’t stop laughing help😭😭😭 you guys are amazing 😂❤️

[@ayushkumarjha5624]

Ok 👍

[@SumanGoswami-zx8wr]

In 18, if we square the sum of the digits we get 9, similarly we can square the digits of 12 and get 9.

[@KPEdutips]

1+8 = 9 , 9² = 81 ?

[@dhanu8391]

Wow really super sir, this trick is most useful for all competitive exams😊👌

[@abhinavmalhotra9981]

Product of means=product of extremes

[@Gitanjalidevi91]

Thnk u Sir. Its helpful

[@GuinnessAndMathGuy]

You are welcome 😊

[@hrittikakumar3172]

9×2 =18 ,
3×3=9
Then..
6×2=12
3×3=9 ....ans is 9 . That was also a trick

[@SampadaGabhud]

It's really useful video 👍👌😊

[@Narendrabhai420]

Ans is 16 because under root 9=3, and 3×6 =18 and under root 16= 4 , and 4×3 =12

[@VishalKumar-zu3ez]

Correct bhai Maine yehi socha tha

[@sschacktricks]

4×3 why??

[@StraightContent]

Kuch bhi???? ..... Bhai, upr wale m 3 ki multiple 6 se krdi aur niche wale m 4 ki multiple 3 se..... Wah bhai wah

[@shaktisharma9759]

3 cube÷3=9
4cube ÷4,=16

[@ranjitbest5412]

18 ka square =324(3+2+4)so, 12 ka square = 144(1+4+4)=9answer

[@guddikumari851]

Tooo good sir

[@AvdheshVyas-ej9lk]

Helpful 💯

[@GuinnessAndMathGuy]

😊

[@JJ_TheGreat]

Wow, that is cool!

[@abrahammg9814]

Principle.product of means and extremes will be equal. So 9×12=18× X. So X =12×9)÷18=6.

[@shihaberanhikkal7682]

What u mean

[@Living_Islamically_always]

Didn't add up

[@joecacurak5404]

U got it right.😮 18/9as 12/x cross multiply9×12=198 divide by 18=6 common sense.2 9's=18 an 2 6's =12 😮 simple comparison.😊

[@SanahRahman]

Literally I did the same but then I saw 6 is not even in the options that are given
I also did the same so now I can say confidentially we know the basic rules 🙂👍🏻

[@ytshoot]

Thank you so much sir ji

Hello sir please make videos on how to crack crossover test specially maths

[@vijayababuaddanki6889]

May be one of the model
18×9=162 1+6+2=9
12×9=108 1+0+8=9

[@Dj_raju999]

Please tell me the more about reasoning question

[@bleed7579]

It's like making 7 to make thala for a reason

You are welcome 😊

[@Alex_Cara77]

So what simbol suppose to be in the middle a new sible meaning take the sqare of the top and subtract the denominator, i didn't know this operational symbol exists

[@muhammadibrahimsoomro1089]

It will be 6

[@ShankarAr-ng6rz]

Nice

[@vishakhv4564]

9*2=18
12*3=36

[@abrahammg9814]

Answer is 6

[@Legend420gaming]

I got the same answer too, but there is no option like that

[@mackisbrocklesnar]

question is flawed

[@sonughosh2793]

36

[@Prabhatkumar-pe9hh]

12 of square 144 = 1+4+4

[@sparkboy5207]

By inspection, we can strike out the 3 extraneous answers except 9 because the answer should be less than 12.

[@GuinnessAndMathGuy]

Genius 😎

[@sanjitsaha9283]

Wonderful

[@GuinnessAndMathGuy]

Thanks 😊

thank you universal

[@ajayabhikirti]

(18)×(18)=324=3+2+4=9,12×12=144=1+4+4=9 is write answer

[@maddurimuralidhararao4931]

It is better to know the principle and solve what you say takes more time than solving it by principle

[@rohankumarnayak5640]

1+8=9(3²)
1+2=3--->3² =9

[@pravinkushwaha2]

18*18=324,3+2+4=9/12*12=144,1+4+4=9 right 👍

[@IPL.HIGHLIGHTS-so5cm]

[@GuinnessAndMathGuy]

You are welcome 😊

[@christembassy_alb]

By what theorem or formula is this going by or we just pulling whatever trick is in the bag. How would I be confident leaving the exam hall after arriving at the answer this way if there was no established formula I was following? 🤷‍♀️

[@arunev3828]

Ultimately what is the use of doing this 🤣

[@milindsalvi4474]

A 9

[@mohamedarafath1425]

Excellent 🎉

[@GuinnessAndMathGuy]

Thanks dear 😊

[@orientcolleges8683]

Answer must be 6. How 9???

[@monoj14]

❤️

[@marinerfasil8935]

9 is the answer

[@user-jg2mw5mv9j]

Love maths

[@protimpatra]

According to law
(9×12)=(18×x)
x=(9×12)/18
x=6

[@bubaibarman4245]

1+8=9,9 ka square 81, reverse 18and 1+2=3,3ka square 9, reverse le likho to to 9 e ayega😊

[@vikramkhemani809]

Wow

[@GuinnessAndMathGuy]

Thanks 😊

[@deepakverma8765]

Option A is the right answer 💯💯💯💯

[@user-ff9qx9em4c]

9×3=18 12×3={36} answer

[@nehanain-zx3gp]

😮😮

[@keshabswain9918]

Sir 5+4 bi 9 hoga

[@ramkhilavankushwaha6679]

9right answer ❤❤

[@user-lt7vh9ig9l]

Rohini Dhabadak answer right 9

[@moments7794]

The pattern here is that in the first pair, 18 is divided by 2 to get 9. Therefore, in the second pair, 12 should be divided by 2 as well.
12 divided by 2 equals 6.
Therefore, the answer is not provided in the choices.

[@selvaganesh-un8dx]

Yes yes add subtract square root divide do all calculation time gone

[@Tirelesswarrior]

The question has value for logical thinking. There are so many ways to think through this...😮

[@Bittu_singh1219]

First square and add every digit

[@GuinnessAndMathGuy]

Exactly 👍

[@user-ie7mj2zx2s]

[@sudhangshubhattacharya4991]

Digit 9 is the joker of such a game

[@uddipandas3335]

12×3=36. 3+6=9
18×3=54. 5+4=9

[@aalekhjain2682]

I would have ticked 9 anyway since answer needs to be smaller than 12 😂

[@risky2707]

12×3=36=3+6=9

[@ShreyanshiSharmaSharma]

18²=324
3+2+4=9
