This is a short answer type question as classified in NCERT Exemplar
Temperature of the source T1= 500K and sink T2= 300K
Work done W= 1000J
Efficiency of Carnot engine = 1-T2/T1= 1-300/500= 200/500= 2/5
Efficiency = W/Q1
So Q1= W/efficiency = 1000

From A to B the process is isobaric

= W = 2 × R (600 - 350)
= 500 R
Heat is path dependent so path function but internal energy does not depend on path chosen.
