Question

can anyone do this plzzzz

Answer 1

Sol: Let the number with two digits be 10x + y. Sum of the digits is 15.⇒ x + y = 15 (1) Number formed by reversing the digits = (10y + x) (10x + y) - (10y + x) = 27 ⇒ 9x - 9y = 27 ⇒ x - y = 3 (2)Solving equations (1) and (2), we get x = 9 and y = 6. Therefore, the original number is 10(9) + 6 = 96.
