Question 1
In a family, Kinsley is the parent of Uma, and Hailey is the grandparent.
Kinsley is 2 times as old as Uma, and Hailey is 20 years older than Kinsley.
What is the age of Kinsley?
Let Uma (child) = 5
Then Kinsley (parent) = 2 × 5 = 10
Then Hailey (grandparent) = 10 + 20 = 30
Then Kinsley (parent) = 2 × 5 = 10
Then Hailey (grandparent) = 10 + 20 = 30
