The approximate output expected in 2016 would be around 1.65 billion.
As the output is expected to be have a decrease of 8.4%, this can concluded that,
100-8.4 = 91.6% of the output,
91.6% = 91.6/100 = 0.916,
91.6% of 1.8 billion is then,
0.916(1.8) = 1.6488
≈ 1.65 billion
Thus, it can be estimated that the expected production would be 1.65 billion in 2016.
