The difference between a number and the number that formed by reversing the digits is 36.if the digit at the tens place is twice the digit at the unit's place.find the number
In the original number let the unit place by x
then the tens place is 2x, (obviously x < 5)
then the number in terms of its value is
10(2x) + x
and the number reversed is 10x + 2x
the difference between these two is 36, just translate this into Math.
10(2x) + x - (10x + 2x) = 36
solve for x
