To solve for the number of marbles Jaalan has, let's denote the number of marbles he has as "m". According to the given information, if Jaalan multiplies the number of marbles he has by 5 and then subtracts 10, the result is 275. Therefore, we can write the following equation to represent the situation:

5m - 10 = 275

Now, we'll solve for "m":

First, add 10 to both sides of the equation to isolate the term with "m":
5m - 10 + 10 = 275 + 10
5m = 285

Next, divide both sides by 5 to solve for "m":
5m / 5 = 285 / 5
m = 57

So Jaalan has 57 marbles. The correct answer is B.
