Among the skills of the superheroes (Spider man ,Batman & Superman) the most useful one in this problem is Peter Parker's (Spider man) ability to crawl upside down, his most famous move. So we have two possibilities Possibility 1-3,6,1. Possibility 2-3,9,1(AS 6 WHEN INVERTED UPSIDE DOWN GIVES US 9). You won't get any answers from Possibility 1, but from Possibility 2, you will have an answer-931 So answer is 931 PS- This is a problem which makes me realize that sometimes reading superhero comics can also help u solve math problems.
