The question is: Christian is twice as old as Brian. In eight more years, Brian will be 40 years old. How old will Christian be in eight years?
Step-by-step reasoning process: If in eight years Brian will be 40 years old, he is currently 40 - 8 = 32 years old. Since Christian is twice as old as Brian, he is 2 * 32 = 64 years old. In 8 years, Christian will be 64 + 8 = 72 years old.
