Answer:

30

Step-by-step explanation:

f = 3(c)

f+20 = c+40

3c + 20 = c + 40

2c = 20

c = 10

f = 3*c = 3x10 = 30

ahh no this is the answer for another question, sorry lol

Answer:

45 Years

Step-by-step explanation:

Let the age of father be x years and sum of the ages of his children by y years.

After 5 years,

Father's age = (x + 5) years

Sum of ages of his children = (y + 10) years

From the given information, we have:

x = 3y ...(1)

and x + 5 = 2(y + 10)

x - 2y = 15 ...(2)

From (1) and (2), we have,

3y - 2y = 15  y = 15

x = 3y = 45

Father's age = 45 years
