The average of 3, 5, 10 and x is 5.
The average of 8, 12, 15, x and y is 9.
Concept:
The average of a set of numbers is the sum of the numbers divided by the number of numbers.
Calculation:
⇒ From the first condition, x = 45 - (3 + 5 + 10) = 20 - 18 = 2
⇒ From the second condition, y = 59 - (8 + 12 + 15 + 2) = 45 - 37 = 8
Therefore, the values of x and y are 2 and 8 respectively.
