The average of 14 numbers is 44. When one more number is added, the average becomes 49. What is the number added?
A. 54
B. 119✓ Correct Answer
C. 49
D. 70
💡 Solution & Explanation
Total of the 14 numbers = 14 × 44 = 616. Total of all 15 numbers = 15 × 49 = 735. The new number is the difference: 735 − 616 = 119. Shortcut: new number = new average + (old count × rise in average) = 49 + 14 × 5 = 119.
