The average of a set of 12 numbers which includes 34 is N. If 34 is removed from the set and 38 is added to the set, what is the average of the new set of numbers in terms of N?
Explanation: প্রথম set এর average \( = N\); প্রথম set এর sum \( = 12N\). দ্বিতীয় set এর sum = \(12N - 34 + 38 = 12N + 4\). দ্বিতীয় set এর average \( = \frac{12N + 4}{12} = \frac{12N}{12} + \frac{4}{12} = N + \frac{1}{3}\).
