Amsar ƙarshe ita ce: 17. <eng> James is 37 - 15 = 22 years old. So 8 years ago he was 22 - 8 = 14 years old. That means Janet was 14 / 2 = 7 years old 8 years ago. So Janet is now 7 + 8 = 15 years old. That means Susan is 15 - 3 = 12 years old. So in 5 years she will be 12 + 5 = 17 years old.
The final answer: 17.
