I think it should be B.
I can buy 8 250-pack for Rs 22.95*8 = $183.60
Now, I can buy 5 20-pack for 3.05*5 = $15.25
Now, I am left with only $1.15. I cannot but anything with this.
Hence Total Hotdogs = 250*8 + 20*5 = 2100

We have $200 and we have to maximize the number of hot dogs that we can buy with this amount.
Let's try to find out what is the maximum number of hot dogs that we can buy for a lesser amount of money, which in this case is 250 for $22.95.
For the sake of calculation, let's take $23. 23x8 gives 184 ,i.e. a total of 250x8 = 2000 hot dogs . We are left with ~$16. Similarly, let's use $3 for calculation. We can buy 5 20-pack hot dogs (3x5), a total of 20x5 = 100 hot dogs. So we have 2100 hot dogs.
2108 looks far-fetched (since we are not likely to be left with > $1.55). Hence, (b) 2100
