Hi Diana!

You could draw out a model to visualise the grandpa's age and the 3 children's ages 10 years later.

Then you can start from the 3 grandchildren's ages but remember to add 30! because all the grandchildren aged by 10 years each.

Find the grandpa's age 10 years later then grandpa's age now. The answer should be 64 years old.

Hope this helps!
