Question
The average of 19 numbers is 15.The average of first 9
numbers are12 and that of the last 9 numbers are15. What will be the 19th number?Solution
Sum of 19 numbers = 19 × 15 = 285 Sum of first 9 numbers = 9 × 12 = 108 Sum of last 9 numbers = 9 × 15 = 135 Therefore, 19th number = 285 – (108 + 135) = 42
