Question

The average age of twelve players of a team is 25. If
the age of captain is also included then the average
age is increased by 1 year. What is the age of cap-
tain?​

Answer 1

Answer:

• average age of 12players is 25
• then totel age of players is 25*12=300
• when one copten is added is average increased by 1 so
• present avg is 26
• totel nbr of players +capten is 13
• totel age of them is26*13=338
• then capten age is =338-300
• so capten age is 38
• because capten +players total age is 338
• and only players age is 330

Answer 2

Answer:

captain age is 38

Step-by-step explanation:

let ages of 12 palyers be x

wkt average is sum of observations by no of observations

$x \div 12 = 25$

now let y be the age of captain and now the total no of palyers are 13 since captain is added

$(x + y) \div 13 = 26$

now by comparing both equations

$12 \times 25 + y = 26 \times 13$

by simplifying we get 38
