Calculating Grandfather's Age

To calculate the age of Oleg's grandfather, we can use the information provided. We know that Oleg is 9 years old, and his age is 25% of his father's age, while his father's age is 60% of his grandfather's age.

Step 1: Calculate Oleg's father's age. Oleg's age = 25% of father's age So, Oleg's father's age = 9 / 0.25 = 36 years old.

Step 2: Calculate Oleg's grandfather's age. Oleg's father's age = 60% of grandfather's age So, Oleg's grandfather's age = 36 / 0.60 = 60 years old.

Therefore, Oleg's grandfather is 60 years old.
