<human>:  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?
<bot>: How old is Maggie? ** Maggie is 3 years younger than Juliet who is 10 years so she is 10-3 = <<10-3=7>>7 years old
How old is Ralph? ** Ralph is 2 years older than Maggie so he is 10+2 = 12 years old
What is the sum of Maggie's and Ralph's ages? ** The sum of Maggie's and Ralph's ages is 7+12 = <<7+12=19>>19 years
