pls mark it as brainliest

so here we go

Step-by-step explanation:

let the two digit number be 10x+y

so digit at ones place be y and tens be x

according to first situation

x+y=3 (1)

according to second case

10x+y=6y

ie 10x=5y

ie y=2x (2)

so substitute in (1) value of y

w get 3x=3

ie x=1

so substitute it in (2)

we get y=2

our number was 10x+y

=(10×1)+2

=10+2

=12

hence required two digit number is 12
