Two different comparisons ("more ... than" and "same ... as") in one sentence

Consider two tasks named A and B with the following properties:

• Task A requires more effort than task B.
• Task A yields as much reward as task B.

I want to say both statements in one sentence. Which of the following are correct? Which one’s the best?

1. Task A requires more effort than task B and yields the same reward as task B.
2. Task A requires more effort than and yields the same reward as task B.
3. Task A requires more effort and yields the same reward as task B.

Basically I want to avoid 1. and I am not sure whether 2. or 3. are correct, if any.
