Question

A number has two digits. The digit at
tens place
is four times the digit at
unit place. if 54 is subtracted from
the number, the digits are
reversed.
find the
mumber.​

Answer 1

Answer:

Thus no is 82

Step-by-step explanation:

Let the digit at unit place =x

then digit at 10's place=4x

Thus number=4x*10+x=41x

If 54 is subtract then number =41x-54

Then the digits are reversed.

means at unit place=4x

and at 10's place digit=x

so the no=10x+4x=14x

As per given

41x-54=14x

41x-14x=54

27x=54

x=54/27=2

So the digit at unit place =x=2 and at 10'splace=4x=8

Thus no is 82

Answer 2

Answer:

N = 82

X = 2
