My lenovo A6000 android phone was stolen with simcard plus memory card inside and I can not remember the IMEI number

Solution
It wouldn't matter if you could remember the IMEI or not. You can't locate the device with that. If you had an app on the phone, or had the phone with a tracking service, then you could try and find it yourself. Otherwise you can't.

You can try contacting your service provider/carrier and see if they can help you locate it. However, even if they can't, you can get them to cut the service to it, before someone runs up your bill. You should also log into every account you access from that device and change all the passwords before someone else locks you out of them.
