The woman's 62-year-old male relative was also injured in the accident, they added.
The incident was reported from northwest Delhi's Rani Bagh.
Shakuntala Devi, a resident of Pitampura, was on her way to Madhuban Chowk from Dipali Chowk along with Ramprakash in an autorickshaw.
A truck laden with Indane gas cylinders passed near the auto at Madhuban Chowk.
In order to avoid hitting the truck, the autorickshaw driver moved a little towards the other side but collided with another autorickshaw.
Ramprakash also sustained injuries in the accident and is currently undergoing treatment at a city hospital.
