Question

The digit at the tens place of a two-digit number is uee
of the number and the number formed by reversing its digits is 88, find the number.
A number consists of two digits. The digit at the tens place is twice that of the digit at units på
8 is subtracted from the number, the digits are reversed. Find the number.​

Answer 1

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
