Jiraiya was 18 when he started training them, he trained them for 3 years. Nagato was 10 when he started training with Jiraiya that means he was 13 when the training ended and Jiraiya left to Konoha and became Minato's Sensei, Minato was 10 as a Genin when he became Jiraiyas student, that means Nagato is 3 years older than Minato. Look at this timeline and its references, Yahiko died age 25-30 and that was the year Obito awakened his Mangekyo
