There is a 27-point discrepancy between the two-digit number and the number generated by swapping the digits. II. There is a three-digit discrepancy between the two digits. III. The digit at the unit's position is three times smaller than the digit at the ten's place.
A. I and II only
B. I and III only
C. All I, II and III
D. Even with all I, II and III, answer cannot be give.
Answer:D
There is a 27-point discrepancy between the two-digit number and the number generated by swapping the digits. II. There is a three-digit discrepancy between the two digits. III. The digit at the unit's position is three times smaller than the digit at the ten's place.
A. I and II only B. I and III only C. All I, II and III D. Even with all I, II and III, answer cannot be give.
Explanation: Let x and y be the tens and units digits, respectively.x - y = 3. I. (10x + y) - (10y + x) x - y = 3.x - y = 3 is the second equation.x - y = 3 is the third condition.As a result, even putting all three assertions together does not yield an answer.
