Question

sum of 2digit is 8when you add 18 the digits get reversed.find the number

Answer 1

➡HERE IS YOUR ANSWER⬇

Let, the digits are a and b.

Then the number be (10a + b).

When the digits are reversed, the number is (10b + a).

Given that :

a + b = 8 .....(i)

and

(10a + b) + 18 = 10b + a

or, 9a - 9b + 18 = 0

or, a - b = -2 = 0 .....(ii)

Adding (i) and (ii), we get

2a = 6

i.e., a = 3

So, b = 5

Hence, the number is 35.
