10 years ago, Amit : Rahul = 6 : 1

First condition,

After 3 years, average age of Amit and Rahul = 20 years

Average = /2 = 20

7x + 26 = 40

x = 2

Present age of amit = 6x + 10 = 22 years

Second condition,

{(6x + 4) / (x + 4)} = 2/1

6x + 4 = 2x + 8

4x = 4

x = 1

Present age of amit = 6x + 10 = 16 years

Data either in statement I alone or in statement II alone is sufficient to answer the question.
