a. 20
b. 25
c. 40
d. 30

Answer 1

Answer:30

Step-by-step explanation: Since 30 can be divided by 6.

                                            Then the son is 5.

                                            In 20 years,he will be 25, so his dad will be 50.

                                           Hope its the correct answer,But is the wrong method.

Answer 2

Answer is 30 I think as

Let the present age of father be 30
Since the age of father is six times of the son’s age the son’s age is 30 X 1/6=5


If we add 20 years to 30 which is present age of father and also add 30 to present age of son

Therefore the age of father is 50 and is half of age of the son whose age is 25

Hence, I think this is the answer
