Explanation

If 1 sack of rice is worth $$\frac{1}{3}$$ of a bushel of tomatoes, buying the whole bushel would require 3 sacks of rice.

Quantity B is equal to 3.

The math is a bit tougher in Quantity A, but no calculation is really required—if a sack trades for 2.5 pounds of beans, a single pound of beans is worth less than a sack of rice. Quantity A is less than 1.

Hence option B is correct!

Absolutely:

1 sac of rice is cheaper than 1 Bushel of tomatoes cos 1/3 bushel of tomatos are would require 3 sac of rice.

For option A

we can logically derive that 1 sac of rice is need to buy 2.5 pounds of beans but the option A states that we simply need 1 pound of beans therefore the less tha 1 sac of rice is required to buy 1 pound of bean.

One need to ask, what is cheap compared to rice.

Thanks
