Answer:
We know Average = sum of numbers/no. of numbers
Sum of numbers = average × no. of numbers
Sum of three numbers = 12 × 3 = 36
Sum of first two numbers = 15 + 10 = 25
The third number = sum of three numbers - sum of two numbers
Third number = 36 - 25 = 11
Thus, the third number is 11
Answer the third number is 11
