Let the no. in tens place be x.
and the no. in units place be y.
Then no. is 10x+y
A.T.Q,
x=3y _______(1)
Also, 10y - x = 10x + y - 36
=> 9y - 9x = -36
=> 9(-x+y) = -36
=> -x + y = -4 ______(2)
Adding equation (1) and (2) we get,
-2y = -4 {since,x gets cancelled}
y=2
Substituting value of y in equal(2)*
-x + 2 = -4
-x = -6
x= 6
So, the number is 10x + y
i.e. 10(6) + 2 = 60+2
= 62
Hope this helps!!!!!

yashdeep9205:
means
i substituted value of y in rquation 2
but you can substitute it also in equation 1
it is ur choice
k thanks
wlc bro
why u have taken 36
it is given that the number reversed is 36 less than original no.
In simple form take original no. as A and reversed as B . So it is given A is 36 less than B. So cant we write it as A = B + 36
thats what i did
