The average of 12 numbers is M and the average of 8 of these numbers is P. If the average of remaining numbers is N then which of the following options is correct?

3M = 2P + N 4M = 2P + 3N 6M = 3P + 2N 6M = 2P + 3N

3M = 2P + N

Sum of 12 numbers = 12M Sum of 8 numbers = 8P Sum of 4 numbers = 4N According to question , 12M = 8P + 4N  3M = 2P + N Hence option 1 is correct .
