The average age of 5 students is taken today it is 14 years . How much it will be taken after 5 years?

Question

Answer

Calculation of Average Age After 5 Years

Given that the average age of 5 students is 14 years. Let's denote the age of each student as A, B, C, D, and E.

Step 1: Finding the Sum of Current Ages

The sum of the current ages of the five students can be found by multiplying the average age by the number of students, which is 5.

Sum of current ages = Average age x Number of students = 14 x 5 = 70 years

Step 2: Finding the Sum of Ages After 5 Years

To find the sum of ages after 5 years, we need to add 5 years to the current age of each student.

Sum of ages after 5 years = (A+5) + (B+5) + (C+5) + (D+5) + (E+5)

Sum of ages after 5 years = (A+B+C+D+E) + 5 x 5 = 70 + 25 = 95 years

Step 3: Finding the Average Age After 5 Years

The average age after 5 years can be found by dividing the sum of ages after 5 years by the number of students.

Average age after 5 years = Sum of ages after 5 years / Number of students = 95 / 5 = 19 years

Conclusion

Therefore, the average age of the 5 students after 5 years will be 19 years.

Answer

(X1 +X2+X3+X4+X5)/5=14
X1 +X2+X3+X4+X5=70
after 5 years ,

(X1 +X2+X3+X4+X5 +5+5+5+5+5)/5=avg.
avg. = 17
