Answer 1

Answer:

First mark me as brainliest please !!!

40 years

Step-by-step explanation:

Let age of father = x ,

age of first child = s1 and

age of second child = s2 .

Ok . so now x = 2(s1 + s2)

After 20 years ,

x + 20 = 40 + s1 + s2

x = s1 + s2 + 20

SO ,

s1 + s2 +20 = 2s1 + 2s2

20 = 2s1 + 2s2 - s1 - s2

s1 + s2 = 20 years

2(s2 + s2) = 2*20 = 40 years

So , age of the father = 40 years
