When i was 4yrs old,my brother was half my age,now i am 25yrs old,how old is my brother now? 


When you were 4 years old, your brother was half your age; meaning he was 2 years old. So the age gap between you two is 2 years. Now that you're 25 years old, your brother is still 2 years younger. So he is 23 years old.
