Output only 230 mV instead of 5V in non-inverting summing amplifier circuit—why?

Can somebody tell me whats wrong in this circuit. Ideally I should be getting output voltage as 5 V but I am getting 230 mV.

What power supply voltage are you using? What op-amp?How are you measuring the output voltage?

Anjali... the most obvious problem I could see was that your Non-Inverting input does not have any path to ground.  I ran your circuit in Multisim as follows
Sorry - it's a bit small.  Now as you see I put in a 1K resistor to ground from the NI input.  This should have the effect of reducing the gain by half so you should get a 2.5V output, however it is 2.74 V as you see.I also tried removing R4 and I got an output of 5.225V.  So this is what you should have got.I am at a loss to find where the discrepancies come in...I have a theory but need more time to work through it.  I think it is because this is a Non-Inverting configuration (in fact effectively it is a differential amp) so the gain equations are not quite the same as the inverting configuration.I'll try and come back to this a bit later, but meantime you should be able to get these results, I suspect you have a wiring fault or bad component somewhere if you do not get these.

Anjali apologies - your configuration should work (but then it did - kind of - with the Multisim simulation).I found an excellent article on it here;https://masteringelectronicsdesign.com/the-transfer-function-of-the-summing-amplifier-with-n-input-signals/
As you can see the maths gets quite involved.  Much easier to use the usual inverting summing amp configuration

David, remove R4 from your Multisim simulation, and you will have Anjali's circuit. My hand-calculations of Anjali's circuit give Anjali's 5.0v output.

This circuit is fine theoretically, but offset voltage needs to be considered in the real world with the high DC gain the circuit has.Cheers,Richard

Yes maybe that was the case, when I wired it again I got the correct results. Thank you so much for the response

Anjali - glad you are getting somewhere.  As an aside, I did the calculations for the non-inverting 2-input summing amp as shown here and you should get exactly 5V out.Where my 5.225V in Multisim came from, heaven knows.  But the late great Bob Pease had a healthy distrust of circuit simulations.  He once said   "My favorite programming language is ... solder."  It's hard to argue with that when you get crooked results like I obtained,
