Question

For 2 digit number ab, ab-ba when divided by a-b gives quotient as:
A) 111. B) 99. C) 11. D)9​

Answer 1

Answer:

(b) 11 gives quotient as a + b. 3. If ab is a 2-digit number, then ab – ba, when divided by (a) a – b gives remainder as 9. (b) 9 ... For a 3-digit number abc, abc – cba = 99 × (a – c) or 9 × 11 × (a – c). 7.
