Here we are providing answers to some important extra questions for students of classes 9 and 10 for mathematics. This is an important question for students of class 10 for chapter 1 , real numbers.

Some other very important questions from real numbers chapter 1 class 10 have also been solved and are mentioned below with their links. All the students are requested to kindly view these questions as well and go through these questions and ask me any doubt relating to chapter 1 class 10 in the comment box.

1) If m and n are odd positive integers, then m^2+n^2 is even, but not divisible by 4. Justify

2) Prove that the product of three consecutive positive integers is divisible by 3

3) Let a and b be positive integers show that root 2 always lies between a by b and a + 2b by a + b

4) Show that there is no positive integer n for which √n-1 + √n+1 is rational.

5) find the smallest number which leaves remainder 8 and 12 when divided by 28 and 32 respectively

I really appreciate it. thanks !! very easy to understand what u teaching!!

[IZhar_jafri]

Sir if given GCD of two numbers is 27 and LCM is 81 how to find tha sum of two numbers

[RohitGupta-sqgq]

Nice explanation sir I liked it too much

[MominaIlyas-svph]

If we take common from x and y, don't we get 15 as common and when we take it to the other side, 180*15/15 will be 180, right? Why did u take 15 twice when u took common in 15x and 15y?

[eriaslukwago]

Thank you very much. You're a life saver!

[pavithram]

Sir., if I get xy in the form of fraction.. What to do at that time???

[meghnadbug]

Sir what is the answer of 'The G.C.D and L.C.M of two numbers are 8 and 320 respectively. Find the difference between two numbers.' Sir please give fat reply.

[utkarshpanchal]

Thanks sir...you are literally great...superb👌👌...thanking you everyday, as I am watching your video everyday too...just wanna say keep going on sir...once you'll seriously be very famous. I am just in class 9th but I am feeling that I have completed 9th's maths, and must start with 10th studies...don't you feel this by your teaching?

[yunfan]

omg i finally understood it after your video . thanks!

[frimmitten]

thank you so much. love from london. video was so helpful!

[sourajyaray]

Is it possible that 2 nos have HCF 7 and LCM 24? Your videos keep me motivated sir, thank you so much

[amarjitsinghsingh]

A very good explanation of HCF and LCM of two numbers

[dhillonhira]

Sir i think (3, 4) liye jayenge wo ryt hoga.
12/1=12 not co prime
4/3= co prime

[saritamahato]

can u help me solve this:
The HCF and LCM of two numbers are 15 and 180. respectively. If they are in the ratio of 3:4, find the number

[sunil]

If HCF is 37 and multiplication of two numbers is 47, 915 ... Can you please find the two numbers ??

[nikhi_]

Sir please solve my problem ..is it possible to have a pair of number whose HCF is 12 and LCM is 220

[kristopherortiz]

bro! great job in explaining this!! really great video.

[saurabhpaswan]

What is the value of x and y whose HCF is 4 n, LCM is 48 n, and if 2 is added to y HCF increases by 2. If 2 is subtracted from x, is it’s HCF reduced by 2? Solve it

[vidyajadhav]

Thankyou Sir!I could solve my problem now.

[strdinesh]

If m & n are two numbers then their LCM is what ?( Let HCF (m, n)=HCF ).
