I see. So we have to first deduce the willing to pay price and then work out TR after? Thanks

<p>For this question the answer is b which is the TR of group 2. If price is the same, my question is why isn't the demand function of group 1 considered? Why is the TR of group 1 omitted?</p>

To sell 45 units to group 2 implies a price of $220-2Q\_2=130$. At that price, demand from group 1 is zero. Indeed, the very most any consumer in group 1 is willing to pay is $100$.
