Expert Answer:

Let the sum  of the ages of the two children = x years

Then, father's age = 3x years

After 5 years the sum of the ages of two children = x +10

After 5 years       father's age = 3x +5 

According to question,

2( x +10 ) = 3x +5

2x +20 = 3x + 5

x = 15

Therefore  father's present  age = 3x = 45 years
