Answer:
37 years
Step-by-step explanation:
If the mean age of 5 people in that room was 25 years,
∴ Sum₍₅₎= (25×5)years
= 125 years
When a person enters that room, the mean age was now 27.
∴ Sum₍₆₎=(27×6) years
= 162 years
∴ The age of the person who entered the room = Sum₍₆₎ - Sum₍₅₎
= (162-125) years
= 37 years
∴ The age of the person who entered the room is 37 years.
