Step-by-step explanation:

Let one's place = y

Tens place = x

Number = 10x + y

ACC TO QUESTION

x + y = 12...(1)

when digits are reversed

new number= 10y + x

Acc to qúéßtions

New no = original number + 36

10y + x = 10x + y + 36

9y - 9x = 36

Adding 1 and 2

2y = 16

y = 8

put in equation 1

x = 4

number = 48
