The difference between a two-digit number and the number obtained by interchanging the two digits is 63. Which is the smaller of the two numbers?

Answer»

Cannot be DETERMINED



Let the ten's DIGIT be x and units digit by y.

Then,

(10x + y) - (10Y + x) = 63

9(x - y) = 63

x - y = 7

Thus, none of the numbers can be determined.
