Let s assume T=7x & B=3x
Hence the diff is 4x
now 4x=84 =>x=21
hence 7x=21*7=147 (B)

Option 1:

Given ratio \(\frac{taco}{burrito}\) = \(\frac{7}{3}\). If we have to find total tacos or burritos then we will do either total tacos =\(\frac{7}{10}\) or total burritos = \(\frac{3}{10}\).
Both implies that the total will be a multiple of 10. Looking at the answer choices only 210 is a multiple of 10 hence (D).

Option 2:

Given ratio \(\frac{taco}{burrito}\) = \(\frac{7}{3}\) -> \(\frac{t}{b}\)=\(\frac{7}{3}\). Given, t=b+84. Substitute 't' in the equation \(\frac{7b}{3}\)=b+84 -> 4b=84*3 -> b=63.
Solve for 't' =\(\frac{7b}{3}\) -> \(\frac{(7*63)}{3}\) -> 147.

t+b=147+63=210 hence (D).

We can create the ratio burritos : tacos = 3x : 7x, and thus:

7x - 3x = 84

4x = 84

x = 21

Thus, 21 x 7 = 147 tacos were sold.

Answer: B
