Question

The average age of 5 students is 10 years. A student aged 14 drops out, find the new average
of the remaining 4 students.​

Answer 1

Answer:

9

Step-by-step explanation:

Ages BEFORE the student leaves = 14, 6, 10, 10, 10

Ages AFTER the student leaves = 6, 10, 10, 10

Average = 6 + 10 + 10 + 10/4

              = 36/4

              = 9

Ages BEFORE the student leaves = 14, 6, 10, 10, 10

Ages AFTER the student leaves = 6, 10, 10, 10

Average = 6 + 10 + 10 + 10/4

              = 36/4

              = 9
