The sum of the digit of a certain two-digit number is 12. Reversing its digit increases the number by 36.find the number
1 answer:
Hello!
You can put down all the single digits that add to 12
3 + 9 = 12
4 + 8 = 12
5 + 7 = 12
6 + 6 = 12
The possible numbers are 39, 48, 57, or 66
You flip all the numbers and find out if it goes up by 36
93 - 39 = 54
It is not 39
84 - 48 = 36
Since it went up by 36 the answer is 48
The answer is 48
Hope this helps!
