The given table shows the production of foodgrains A, B and C and their export (as a percentage of production) over five years from 2015 to 2019, Study the table and answer the questions that follow.
Production = Domestic Consumption + Export
Question 57
What is the ratio of the total export of foodgrain A in 2015, 2016 and 2019 to the total export of foodgrain B in 2016 to 2019?
Solution
Export of A in 2015, 2016, 2019 are
$$320\times\ 0.35=112$$
$$350\times\ 0.30=105$$
$$450\times\ 0.34=153$$
Total : 370
Export of B from 2016 to 2019:
$$200\times\ 0.42=84$$
$$350\times\ 0.34=119$$
$$320\times\ 0.30=96$$
$$300\times\ 0.27=81$$
Total : 308
Their ratio = $$\frac{370}{380}=37:38$$
Hence, Option A is the correct answer.
