Answer:
Let tens place be x and one’s be y.
So the number is 10x + y.
x = 3 times y. => x - 3y = 0 -> (1)
The interchanged number is 10y + x.
So, on adding, we get 11x + 11y = 88
Or x + y = 8 -> (2) (on dividing whole by 11).
Now we have to subtract. So we get 4y = 8. Therefore y = 2, and x = 8-2 =6 (from 1st eq.)
Hence the answer is 62 and 26.
Hope the answer helped you. Pls mark as brainliest! :)

Answer:
The original number will be 26 or 62
Step-by-step explanation:
Let one digit be x
So, the other digit is 3x
The number formed will be 10x + 3x = 13x
After interchanging the digits,
(10×3x) + x = 30x + x = 31x.
After adding both numbers,
13x + 31x = 88
44x = 88
x = 2.
So,
The number formed is (10×2) + (3×2) = 20 + 6 = 26
Or it can also be 62
