The sum of the digits of a two-digit number is 12. if 18 is subtracted from the number, then the digits interchange their places. Find the number. The following steps are involved in solving the above problem. Arrange them in sequential order. (A) Units digits is 5, tens digit is 7, and the number is 75. (B) Given that 120-9x-18=9x+12rArr90=18xrArrx=5 . (C) The number formed by interchanging the digits is 10x+(12-x)=9x+12 . (D) Let the digit in the units place be x. Then the digit in the tens place be (12-x). therefore The number is 10(12-x)+x=120-10x+x=120-9x .
