Juliet is 3 years older than her sister Maggie but 2 years younger than her elder brother Ralph. If Juliet is 10 years old, what is the sum of Maggie's and Ralph's ages? Let's answer step by step:
Maggie is 3 years younger than Juliet who is 10 years so she is 10 - 3 = 7 years old. Ralph is 2 years older than Maggie so he is 10 + 2 = 12 years old. The sum of Maggie's and Ralph's ages is 7 + 12 = 19 years. The answer: 19.
