Can You Solve This GATE Question? | Part 5

Can You Solve This GATE Question?
Picture a single-elimination tournament with 128 participants, and you need to determine the total number of matches to find the ultimate winner. It might seem like a massive calculation, but each match eliminates exactly one player, so you need 127 matches to eliminate 127 participants. This logic-based puzzle highlights the elegance of GATE exam questions: they can appear complex yet rely on a fundamental insight. Preparing for GATE means you’ll encounter such scenarios that test reasoning, aptitude, and conceptual clarity across engineering domains. Strengthening these skills can lead you to prestigious postgrad programs or PSU roles where analytical thinking is prized.

No way they asked this 4th standard question in GATE

[@Sarwadnya118]

It also follows the sequence 1×2=2, 2×3=6, 3×4=12, 4×5=20, 5×6=30 and 6×7=42

[@susheelkrishna2727]

Exactly! Even I thought this😅

[@rudrathakur6253]

Also n^2+n

[@mr_crew19]

nice 👍

[@Sarwadnya118]

@@rudrathakur6253 yuppie 👍

[@rockyroad3007]

n=n+2 sequence

[@abdurrahmanfaisal4645]

For the first time I can solve before check the answer 😅😂

[@Moana2yaey]

Same

[@ummehanisami-e1f]

right😂😂😂

[@inamdar_ria]

When we were in school, there was an examination called 'scholarship' it was the same question which was difficult for me at that time. But today, I Found it very easy 👍

[@an._2407]

Yeah..! Aapne scholarship exam kon se std me diya tha?

[@Suryawanshi08]

It also follows the sequence 2²-2 , 3²-3 , 4²-4 ,5²-5 then 6²-6 and 7²-7 = 49 -7=42

[@riddhigupta229]

2×1=2 Now leave one(2×2) 2×3=6 Now leave two(2×4,2×5) 2×6=12 Now leave three(2×7,2×8,2×9) 2×10=20 Now leave four(2×11,2×12,2×13,2×14) 2×15=30 Now leave five(2×16,2×17,2×18,2×19,2×20) 2×21=42 Therefore, 42 is answer

[@neerajChandola-px5ci]

1^2+1=2,+2^2+2=6,+3^2+3=12,+4^2+4=20,+5^2+5 = 30 and finally 6^2+6=42

[@humaira2651]

I thought the same 😅

[@williamsheksphere6679]

Ek aur method se solve kar sakte hai Sequence mai number and uska square root add hai 1+1²,2+2²,3+3²,4+4²,5+5².... That's why my answer comes 6+6²=42

[@SagarKunte-24]

See the difference between numbers it was very easy first it was 2,4,6,8,10 and after 30 the difference should be 12 so add 12 to 30 and the answer is 42😊

[@SagarKunte-24]

I solved this question before watching the vedio 🎉

[@chintusharma1]

Good way to teach question

[@anilgurjar9813]

1+1^2 , 2+2^2 , 3+3^2 , 4+4^2 , 5+5^2 so the next one is 6+6^2= 42

[@hmeshram201]

very very simple answer is 42 6-2 = 4 12-6=6 20-12=8 30-20=10 next would be x-30=12 hence x=42

[@saifiqbal5921]

Another way to solve this question is to add numbers in this given sequence. Like 2+4=6 , 6+6=12, 12+8=20,20+10=30, 30+12=42 means we add 4 in first number and get the second number in sequence and add 4+2=6 into 6 and get next number in the sequence and then add 6+2=8 into 12 and get next number and so on. We add 4,6,8,10,12 into numbers of sequence and get the next number in the sequence. This sequence is A.P.

[@MahinAnsari-dz4sg]

42 answer

[@ANONYMOUS21140]

Every terms are overlapping previous term by a sequence of 2 more than the previous difference therefore the last difference of the sequence is 12 and 30 +12 is 42 which is the answer .

[@kishankumarhazari3692]

2 2+2+2= 6 6+2+2+2 =12 12 +2+2+2+2= 20 20 +2+2+2+2+2= 30 30+ 2+2+2+2+2+2= 42

[@pandurangpatil9151]

42 is the correct answer cuz difference between each number is by table of 2

[@Aayushgulati0711]

We can also answer by adding 2 number extra 4+2=6 6+4+2=12 like this
