The average of 3 numbers is 45. Two of the numbers are 55 and 30. The third number is?
Explanation
50 is the correct answer
According to the given information, the average of the three numbers is 45. We can calculate the average by summing up the three numbers and dividing by 3: (55 + 30 + x) / 3 = 45 Now, we can solve this equation to find the value of "x": (55 + 30 + x) = 45 * 3 85 + x = 135 x = 135 - 85 x = 50 Therefore, the third number is 50.
