Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e 8
Trade balance in 2016 = 130 - 125 = 5
Trade balance in 2017 = 150 - 145 = 5
Trade balance in 2018 = 175 - 165 = 10
Trade balance in 2019 = 200 - 188 = 12
⇒ Average of trade balance = (5 + 5 + 10 + 12) / 4
⇒ 32 / 4 = 8
