One of the two digits of a two number is two times the other digit if t interchange the digits of this two number and add the resulting number to the original Number you get 99 what is the original Number

Posted by Mangkholian Vaiphei 4 years, 11 months ago

Sia ? 4 years, 11 months ago

Let the digits at tens place be x.

And ones place be 3x .

Original Number = 10x + 3x = 13x

Number after interchanging = 10 × 3x + x = 30x + x = 31x

According to the Question,

⇒ Original number + New number = 88

⇒ 13x + 31x = 88

⇒ 44x = 88

⇒ x = 88/44

⇒ x = 2

Original Number = 13x = 13 × 2 = 26

Therefore, by considering the tens place and ones place as 3x and x.

The two digit number obtained is 62.

Hence, the two-digit number may be 26 or 62.
