Step-by-step explanation:
Let Father's age be F.
Age of Child 1 = s
Age of child 2 = c
As per data
- F= 3(c+s)
- F+5= 8 + 3c i. e. F = 3+ 3c
equate above equations
we get 3c + 3s = 3 + 3c
I. e. 3s = 3
s = 1
Now we get F = 3(c+1)
put any natural no. above 18( you know why) for F and solve equation
like C = 6, S = 1 , and F = 21
