My head is spinning after reading the question 😂

[anilkumarprasad]

I can explain this question,
See..the two digits numbers are (10x+y) and (10y+x)
Then, their sum will be 10x+y+10y+x
That is 11x+11y which can be written as 11(x+y)
Now, before solving it further you must know what is perfect square, it is the product of two SAME integers i.e. for eg, 25 is a perfect square which is the product of 5 and 5
So you can see 5 and 5 are same
So for this question x+y=11 as we already have 11 as first integer So to make it perfect square the second integer i.e, (x+y) must be 11
And hence, x+y =11
I hope you liked my explanation!!😊

This is my explanation:

Let's consider two-digit numbers formed by using the digits x and y. The general form would be 10x + y and 10y + x. The sum of these two numbers is:

10x+y+10y+x=11x+11y=11(x+y)

For the sum to be a perfect square, the value of (x + y) must be a multiple of 11. The smallest pair of different digits satisfying this condition is (5, 6). Therefore, the value of x + y is 5 + 6 = 11.

Thankuuuu bhaiya maths toh aap or accha padha rahe ho🙏🤓🤓🤓 app bestttt ho really😍😍

[rehnumashaikh]

As a chaitanyan I luckily answered this. I'm poor in maths but I got to know that my schl has provided every type of question!!

[by_justice]

The square part actually confused me but this was a nice question. Thank you :)

[PalakShukla-zxzc]

Thank you ma'am for explaining this question 😊

[suchitrasamal]

Option d since the sum of it's digits is 4 which is a perfect square

[Palak_]

to. 😅😅😅🔥
My head right now 🥚👀☠️☠️☠️☠️

My head is spinning after reading this question

[nazfasions]

While i used this method
If we take a random option which is 11 and if we cut it into two parts randomly which is 6+5 if we do it like this 65+56=121 which is a perfect square
While if we try the same process on others it will not work like if we took 10 then 6+4
64+46=110
Which is not a perfect square number
😅😅😅
If you like my procedure then

[pushpajha]

Ma'am I have a doubt in this question it is not mentioned that x and y are two digit no then how did you take it as two digit no

[khushboosingh]

it was easy. thank you ma'am love you yaar byjus

[T_GungunTagore]

Thankyou mam for explaining this question:)

[Sampoorna.]

Easy peasy lemon squeezy!
