Sum of all 30 terms = 30 x 55= 1650 Sum of first 15 terms = 15× 50 = 750 Sum of last 12 terms = 12 x 55 = 660 After removing the first 15 and last 12 terms, there will be 3 terms remaining. Sum of remaining 3 terms = 1650 (750 +660) = 240 According to the question, 68 and 74 are added to the sum of 3 terms. Thus, the number of total terms becomes 5. Average of 5 terms = (240 +68 + 74)/5 382/5= 76.4 76.4 is the average of 68, 74 and the remaining 3 numbers.
