Sum of two digits of a number is 7. When 27 is subtracted from this number, its digits get interchanged. Which of the following are correct steps to find the number?

I. Let tens digit be m.

II. Then, ones digit = (7 - m)
Number = 10 × m + (7 - m) = 9m + 7

III. Subtracting 27 from the number, we get 9m - 20.

IV. Number with its digits interchanged = 10 × (7 - m) + m

V. 9m – 20 = 70 – 9m

VI. Hence, the number = 52
