The average of 15 numbers is 30, while the average of 13 of these numbers is 32. If the remaining two numbers are equal, then what is each of the two numbers? |
34 31 17 16 |
17 |
Sum of 15 numbers = 15 x 30 = 450 Sum of 13 numbers = 13 x 32 = 416 Sum of remaining 2 numbers = 450 - 416 = 34 Each of the two numbers = 17 |
