Question

sum of Ages of a father and the sun is 40 years the father's age is three times that of his son then find a respective wages​

Answer 1

Answer:

Age of son = 10 , Age of father = 30

Step-by-step explanation:

Let age of father be 'f'

Let age of son be 's'

Therefore, f+s=40 & f=3s

Putting f=3s in f+s=40,

3s+s=40

4s=40

s=10

Therefore, f=3s= 3(10) = 30

Hence, Age of son = 10 , Age of father = 30

Answer 2

let the age of father be x and son be y

Now,the sum of their ages is 40

i.e. x+y=40....(i)

again.fathers age is 3 times that of his son

x=3y...(i)

x+y=40

x=40-y

putting the value of x in eqn ii

40-y=3y

y=10years

sons age is 10 yrs,

where fathers age is 3*10=30 years
