The pie charts given below depict the percentage productionbreakup of 4 crops viz maize, corn, soyabean and wheat in the world and USArespectively. Assume that the total world production of these crops in a given year is160 million tonnes.
In all the questions, 'ROW' means rest of the world other than USA.
Given that USA accounts for 20 percent of the total production of soyabean in the world then what percentage of the total food crops production of the world is accounted by USA?
Given: 20% of total soyabean production of the world is from USA
Thus, Let the total world production of crops be P.
Thus, USA's production of soyabean = 0.2 x 0.35 x P = 0.07P = 7% of the total productions of crops.
Soyabean productions consitutes 25% of the total crop production in the USA.
Thus, percentage of total crop production accounted by the USA = $$\frac{7\%}{0.25}=28\%$$
Hence, the answer is option C.
