80. A Question is given followed by two Statements I and II. Consider the Question and the Statements and mark the correct option. Question : Let XYZ be a 3-digit number and the difference between XYZ and ZYX is equal to PQR. Is (P + R) equal to Q ? Statement-I : P = 3 Statement-II : R = 6

  1. A. The Question can be answered by using one of the statements alone, but cannot be answered using the other statement alone
  2. B. The Question can be answered by using either Statement alone
  3. C. The Question can be answered by using both the Statements together, but cannot be answered using either Statement alone
  4. D. The Question can be answered even without using both the Statements ✓

Correct Answer: D. The Question can be answered even without using both the Statements

Explanation

The difference between any 3-digit number and its reverse is always a multiple of 99. For 3-digit multiples of 99, the middle digit (Q) is always 9, and the sum of the outer digits (P+R) is always 9. Therefore, P+R=Q is definitively true without needing any statements.
