Answer 1

Answer:

Let one’s digit be x. Since the sum of digits is 12. Therefore, ten’s digit = (12 – x) ….(i) ∴Number = 10 x ten’s digit + One’s digit = 10 (12 – x) + x = 120 – 10x + x = 120 – 9x Now, if digits are reversed, then One’s digit = 12 – x and ten’s digit = x ∴ New number = 10 x ten’s digit + one’s digit = 10(x) + 12 – x = 10x + 12 – x = 10x – x + 12 = 9x + 12 According to question, ⇒ 9x + 12 = (120 – 9x) + 54 ⇒ 9x + 12 = 120 + 54 – 9x ⇒ 9x + 12 = 174 – 9x ⇒ 9x + 9x = 174 – 12 ⇒ 18x = 162 ⇒ x = 162/18 ⇒ x = 9 One’s digit = 9 and ten’s digit = 12 – 9 = 3 Hence, the required number = 39
