Answer:
11
Step-by-step explanation:
We know Average = sum / no. of numbers
Sum = average × no of number
The average of three numbers is 29, thus their sum
Sum = 29 × 3 = 87
The average of two of these numbers is 38. Their sum.
The sum of two of these numbers
Sum = 38 × 2 = 76
The third number = sum of three numbers - sum of two of these numbers
Third number = 87 - 76 = 11
The third number is 11.
