In a family with four children, Maya was born 3 years before Ethan. Chloe was born 2 years after Maya. Noah was born 4 years before Chloe. Who is the oldest child?
Noah
Let Maya's birth year be Y. Ethan was born in Y + 3. Chloe was born in Y + 2. Noah was born 4 years before Chloe, so in year (Y + 2) - 4 = Y - 2. An earlier birth year means an older age, so Noah (born in Y - 2) is the oldest.
