GPSC (Gujarat) — MCQ Practice Questions & Answers

Question 1

A two-digit number is such that the sum of its digits is 11, and when 27 is subtracted from it, the digits are reversed. What is the number?

Accepted Answer

Correct answer: D. 92 — Let the number be 10a + b. Given: a + b = 11 and 10a + b - 27 = 10b + a. Solving: 9a - 9b = 27, so a - b = 3. From a + b = 11 and a - b = 3: 2a = 14, a = 7, b = 4. Wait, let me recalculate: a = 9, b = 2. Number = 92. Check: 9 + 2 = 11 ✓ and 92 - 27 = 65 (which is 29 reversed, not matching). Actually a = 9, b = 2 gives 92 - 27 = 65, but 92 reversed is 29, not 65. Let me re-solve: 10a + b - 27 = 10b + a means 9a - 9b = 27, so a - b = 3. With a + b = 11, we get a = 7, b = 4, giving 74. Check: 74 - 27 = 47 ✓
