Know when punishments run concurrently and when it runs consecutively. if a criminal beats a victim and then rapes her, the punishment for 3 years for beating and for rape for 10 years will be concurrent. So ultimately criminal will suffer 10 years only. But if he beats victim in the morning and then rapes her in evening, these two crimes will be treated separately. Punishment will be consecutive. He will have to suffer 10 years + 3 years total 13 years.
