Question

In a two digit number. The tens place digit is three times more than the digit in unit's place. If the digits are reversed, the new number becomes 36 less than the original number. Find the number.​

Answer 1

Step-by-step explanation:

let the unit place be x then ten's place= 3x

number= 10(3x)+x

= 30x + x

= 31 x

according to question,

31x - 36= 10x + 3x

Or, 31x - 36 = 13x

Or, 31x -13 x= 36

Or, 18x = 36

x = 36/18

= 2

number = 41x

= (41*2)

= 82
