Step-by-step explanation:
Let the number 10a+b then b-a =2 …… (1)
If you reverse the number then it is 10b+a, their difference is
= (10b+a)-(10a+b) = 9(b-a)= 18 which is always true because of (1)
So there is no addl info to solve the question
To state differently, any number, which satisfies (1), when it is deducted from its reverse will leave 18
Take 13 (3–1=2) & 31–13 = 18, take 24 (4–2=2) & 42–24=18, take 35 (5-3=2) & 53–35=18
please add me in the brainly list.
