A two digit number is such that the sum of digitis ten if the digits are reversed the new number formed is less than original number by 18 find the number
Let the two digits be represented by 10x + y, where x and y are the digits.
Given that the sum of the digits is 10:
x + y = 10 (1)
When the digits are reversed, the new number is 10y + x.
Given that the new number is less than the original number by 18:
10x + y - (10y + x) = 18
9x - 9y = 18
x - y = 2 (2)
Now we have a system of two equations:
x + y = 10
x - y = 2
Adding the two equations together, we get:
2x = 12
x = 6
Substitute x = 6 into equation (1):
6 + y = 10
y = 4
Therefore, the number is 64.
