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.
Assume that the total production of maize in the USA is 3 million tonnes. Calculate the percentage (approximately) of the total production of food crops in the world accounted by the USA?
The total production of maize in the USA is 3 million tonnes and maize constitutes 40% of the total production of the USA.
Thus, total crop production in the USA = $$\frac{3}{0.4}=7.5$$million tonnes.
Thus, the percentage of the total production of crops in the world accounted for by the USA = $$\frac{7.5\times100}{160}=4.68\%$$
Hence, the answer is option B.
