Question

average of Jay and Veeru is 20 years the average age after 5 years

Answer 1

Answer : 25,

Here is the solution :

Average (or) Mean =
(Sum of Observations)/No. Of Observations

Here Sum of Observations = Sum of ages of Jay and Veeru,

No. of Observations = No.of Persons = 2,

Let age of Jay be x,
and age of Veeru be y,

According to Question,

(x+y)/2 = 20 years,

=> x+y = 40 years,

Sum of their ages = 40 years,

After 5 years,
Jay's age = x+5,
Veeru's age = y+5

=> Sum of ages after 5 years = x+5+y+5,

=> x+y+10

=> 50, (Since x+y = 40),

Now,

Average of their ages after 5 years is,

50/2 (Formula)

=> 25,

Therefore : Average age after 5 years is 25 years,
