Important questions
share it a link alone
Don't waste my hardwork and valuable time
Don't share as screenshot kind request
most viewed dept will get update at first So Dont screenshot and share
*These questions are expected for the exams This may or may not be asked for exams .
All the best....
Thanks for your love and support guys keep supporting and share let the Engineers know about Us and leave a comment below for better improvements If there is any doubt feel free to ask me I will clear if I can or-else I will say some solutions ..get me through WhatsApp for instant updates ~$tuff$£ctorsUNIT-1 METAL CASTING PROCESSES
