Answer 1

Answer:

Let the original number be xy = 10x+y

Digit on 10's place be - x

Digit in unit 's place -y

Given :-

x = 4 y

Reversed number = yx = 10y+x

yx = xy - 54

10y + x = 10x + y - 54

9x = 9y + 54

x = y + 8

x = 8 y

8y = y + 8

y = 1

x= 4( 1 ) = 4

therefore , original number = 4 .
