In the first stage of a two-stage Carnot engine, energy is absorbed as heat Q1 at temperature

Question:

In the first stage of a two-stage Carnot engine, energy is absorbed as heat Q1 at temperature T1, work W1 is done, and energy is expelled as heat Q2 at a lower temperature T2. The second stage absorbs that energy as heat Q2 does work W2, and expels energy as heat Q3 at a still lower temperature T3. Prove that the efficiency of the engine is (T1 – T3) / T1
