Number system ke base ka logic kuch iss tarah hota h jaise maan lo apke paas do number h 7 aur 8 aapko unko add (+) karna h aur apka base 10 h toh apne likha 7 + 8 = 15 lekin h 15 aaya kese toh jab aapne 7 count kar liye usske baad aap ussme 8 add karne toh 2 number toh add hogaye aur 9 aaya lekin jaise 3 ra number add karne jaoge aapke base 10 ke saare numbers khatam hojayenge ab apko counting reset karni hogi apke base ke pehele number par joki 0 hota h  yani ab 7 + 3 = 10 hogaya lekin abhi bhi 5 add karne baki h toh aap iss 10 mein 5 add karenge toh 10+ 5=15 hojayega yani 7+8=15
Hum kisi bhi addition ko aise likh sakte h X + Y = b + Z (yaha b hamara base h)
Hum thori der ke liye iss question ka base "b" maan lete h

Agar unit place ko de ke toh □ + 2 = 3
Ab agar unit palce se carry jaa rahi h aisa man liya jai toh □ + 2 = b + 3 hojayega yani □ = b + 1 hojayega lekin yeh galat h kyu ki koi bhi number apane base system nuber se bada nahi ho sakta jeae 2 woh 10 se bada nahi hoga yani koi carry nahi jayegi unit place se aur unit place ka box 1 ho jayega
Ab Tens ke colum ko dekhe toh 5+4 = 9 ho chahiye lekin 2 h iska matlab ismein ek base add huva h yani 9 = b + 2 hoga yani hamara base 7 aajayega aur hume yeh bhi pata chala ki tens se ek carry bhi jayegi ab Hundred ki place ko dekhte h
1 + □ + 6 = 7 + 4 (kyu ki tens se ek carry gai thi aur ab yaha se bhi carry jaiyegi)
□ = 4 (yeh hundreds ki place ka box h)
Ab hume yeh bhi pata chal raha h ki hundreds ke place se carry jaa rahi h thousands mein
Ab thousand ki place ko dekhte h
1 + 3 + □ = 7 + 2 ( LHS mein 1 issiliye likha kyu ki hundreds ke place se carry  gai thi aur agar RHS ko dekhe toh ussme 7 issi liye likha kyu ki ten thousand wale place mein 2 + 1 = 4 likha h yeh tabhi possible h jab thousand ke place se carry gai ho)
□ = 5 ( yeh thousand ki place ka box h)
23451 + 15642 = 42423 (base 7)

Sir, 23551 and 16642 all in base 7. Some is having 23451 and 15642 answer just they have to add 1. Because 7 in base 7 is 10 not 11.

Sir, I think the number on the top is 23451 and the number on the bottom is 15642 and the operation is based on the number system with base 7.

The system is not based on a standard hexadecimal or binary or any other system it is a completely new system whose base is 5 or 6

Sir aise toh sabse right wale box mei 1 hi aa skta h agar box mei only 1 digit numbers allowed h toh
Hence, koi carry bhi nhi hoga, toh 5+4=9 hona chahiye but 2 likha h
Toh mai yeh soch rha hu ki yeh question decimal number system pe based na hoke kisi aur number system pe based h, jaise base 5 ya base 6, etc...
Kya sir meri thinking sahi h?

Sir in this question does the box can only be filled with single digits or double digits can be used ?
If double digits can be used then this question can have multiple sets that can satisfy the condition.

Sir,plz explain and solve this question,find the number of solutions of sin (πx)+x^2 +1=2x,using class 11 trigonometry concepts,I tried to solve it but I was unable if we draw the graph we see that there are two unique intersecting points i.e,two solutions but how to show it without graph by using trigonometry, algebra,etc,we are  easily able to show 0≤x≤2 ,and x=1 is a trivial solution,I was also able to show that there exist no solution for 0<x<1,and x=0,2 (the endpoints) don't satisfy the equation,also we can easily see that for 0<x<2 , solution may exist,but how to proceed from here,this is a pre dpp question of vibrant academy

1. Unit digit is definately "1". For any number base system.
2. Number base is greater than 6.
3. 5+4 = b+2. Can the base be 7 ?
