Study the given graph and answer the question that follows.   In 2019, the production of computers decreased from that in 2018 by the same percentage as in 2018 over its previous year, and the exports in 2019 remained the same as in 2018. What will be the difference (in thousands) between the production and exports of computers in 2019? Correct Answer 33

Calculation:

The production of computers in 2017 = 300

The production of computers in 2018 = 270

The percentage decreased in 2018 over its previous year = (270/300 × 100)

⇒ 90%

Now,

In 2019, the production of computers decreased from that in 2018 = (270 × 90/100)

⇒ 243

The exports in 2019 remained the same as in 2018 = 210

The difference between the production and exports of computers in 2019 = (243 – 210)

⇒ 33

∴ The required difference is 33
