The sum of the two digits number is 15. If the new number formed by reversing the digits is less than the original number by 27 find the original two digit number

Answer»

Step-by-step explanation:

let the tens digit be ' a ' and the ones digit be 'b'

a + b = 15 ( given ) - A

(10*a + b ) - 27 = 10*b + a

implies,

9A - 9b = 27. - B

by 9A + B we get

18A = 135 + 27

so we get,

a = 9

b = 6

so the NUMBERS are 96 and 69
