I think the confusion arises due to difference in equations from Physics and Chemistry text books.

The physics text writes $U=q-w$∆U=q-w while chemistry says $U=q+w$∆U=q+w.
From the physics text its mentioned that work done by the system is positive means $U=q-(+w)$∆U=q-(+w) and work done on the system is negative means $U=q-(-w)$∆U=q-(-w).

THEREFORE, both are correct in their own way. Hope I've figured it out correctly.
