Day by day this Coaching institute is shining between who can’t afford coaching 🙏 thanks to all teachers especially Rishab sir🎉

[@INDIANfrommaharastra]

For those who don't understood last question 👍👍✍️
See we have two digit number
ab means 10a +b according to representation rule
After reversing it becomes
10b+a and the difference between them is 27 ,so
Evaluate
(10a+b) -(10b+a)=27
9a-9b =27
Take 9 common
a-b = 3
So we get an condition
In question they said two digit numbers means digits are from 1 to 9
So place all numbers in obtained equation
1) (a=3,b=0) =3 after (a-c)
2) (4,1)
3) (5,2)
4)(6,3)
5)(7,4)
6) (8,5)
7)(9,6)
7 possible values
I hope you got it❤❤

It is 12 for the last ...we have to count the reversed (numbers) also🤔

[@Ranjit_24]

@@None-lr2cy ok 👍🏻

[@jindalnarnolia8817]

​@None-lr2cy bro, we have to identify the differences between numbers

[@jindalnarnolia8817]

The difference is 3, so 6 pairs formed out of 12 numbers

[@preetipandwar2113]

sir please continues this series for full preparation 🙏🙏🙏🙏

[@codersj06]

last question solution: let original no be xy i.e, 10x+y so reversed no = yx i.e, 10y+x. given that xy-yx=27, so 10x+y-10y-x=27 => 9x-9y=27 => x-y=3 => y=x-3. now start substituting values into x from 0 and respective value of y will be (x-3) like if x=3 then y=0 so no.=30 similarly we'll get 41,52,63,74,85 and 96. So, total 7 such numbers.

[@divyaupadhyay9311]

[@anamikarao1010]

[@nikitasolanki854]

Thank you so much for this session 🙏❤️

[@RadhaKaushik-sw9ib]

The last one question's answer is 3
a+b= 10a+b------- equation (1)
b+a= 10b+a-------- equation (2)
So, the difference between two digits is 27:-
Then,
(10a+b)-(10b+a) = 27
10a+b-10b-a = 27
9a-9b = 27
Let's take 9 common;
9(a-b) = 27(divide by 9)
a-b = 3
So, there are 3 numbers.
😊❤
I hope you understood.

[@ayu24222]

BUT further its asking how many such digits will form???sirf digit nai puchi hai..how many possibilities puchi hai
