Instructions
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.
Question 64
USA produces 20 percent lesser corn than ROW, find the production ofsoyabean in USA?
Solution
Let the total production of crops in the USA, World and ROW be denoted by U, W and R, respectively.
Thus, 0.2(U) = 0.8[0.2W - 0.2U]
0.36U = 0.16W
$$U=\frac{4}{9}W$$
Thus, production of soybean in the USA = 0.25U = 0.25 x $$\frac{4}{9}W$$ = $$0.25\times\frac{4}{9}\times160=17.75$$million tonnes.
Hence, the answer is option D.
