please give answer with solution I give you thanks also brilliant ​

Answer 1

Answer:

Step-by-step explanation:

Let the one's digit be y and tens digit be x,

Number = 10x + y

Then,x=3y⋯(i)

Reversed number = 10y + x

A.t.Q :- (10x+y)−(10y+x)=36 Put x = 3y in eq. (i)

⇒9x−9y=36

⇒x−y=4⋯(ii)

⇒3y−y=4

∴2y=4 x=3y ∴x=6

y=2

∴ Number = 62

Answer 2

Answer:

ones place x

tens place

$\frac{1}{2} \times x = \frac{x}{2} \times 10$

new no. tens 10x

ones

$\frac{1}{2} \times x \times \frac{x}{2}$

original no - 36 =new no

u can solve.

hope it is helpful
