Question

The sum of the digit of a 2 digit number is 12. The number is 6 times the units digit. Find the number.​

Answer 1

Step-by-step explanation:

let tens digit be x and unit digit be y

number formed=10x+y

ATQ,

x+y=12- - -1

10x+y=6y

10x-5y=0

5(2x-y)=0

2x-y=0- - -2

on solving 1&2, we get

3x=12

x=4

on putting value of x in 1 ,we get

y=12-4

y=8

therefore number formed

=10(4)+8

=48
