The following are the ages (years) of 5 people in a room: 24 , 24 , 15 , 16 , 19 A person enters the room. The mean age of the 6 people is now 19. What is the age of the person who entered the room?

16 years old.

Step-by-step explanation:

(24+24+15+16+19+X) / 6 = 19

(98 + X) / 6 = 19

98 + X = (19)*(6)

98 + X = 114

X = 114-98

X = 16
