A set contains ten numbers. The average of the first
six numbers is (x − 6), and the average of the last three numbers is (x + 6). The average of the entire set is 'x'. If the 7th number of the set is 36, then find the value of 'x'.Solution
Sum of the numbers of set = 10x Sum of first 6 numbers = 6(x − 6) = 6x − 36 Sum of last 3 numbers = 3(x + 6) = 3x + 18 ATP, 6x − 36 + 36 + 3x + 18 = 10x 9x + 18 = 10x x = 18
