In which year, the exports of item D were 1.4 times the average exports of item B during six years?
Answer & explanation
Correct answer: option 2
Average export of B = \(\frac{128 + 134 + 138 + 169 + 182 + 209}{6}\)
= \(\frac{ 960}{6}\)
= 160
1.4 times of average export of B = 1.4 × 160 = 224
Export of D in year 2013 is also 224
Ans = 2013
