Question

the average age of 5 children is 5 years. If the age of their father also included, the average age will be increased by 100%. what is the age of father ?

Answer 1

Answer:

35

Step-by-step explanation:

let x = the total age of the children and y = the age of the father,

x/5 = 5

x = 25

when 5 is increased by 100%, it equals 10 so:

$\frac{x+y}{6}=10$

x + y = 60

y = 60 - 25

y = 35
