Oh , I forgot to Add- Jangpura M.S. is on Violet line, which terminates in Central Secretariat M.S. ,from there you have to change onto Yellow line.
Hence for your entire metro travel from Jangpura to Pratap nagar , you will have 2 interchanges - one from Violet to Yellow at Central Secretariat and then Yellow to Red at ISBT kashmere gate.
