Now Calculate for each year = 0+0+0+0+1+0+0+0+1+0+0+0+2+3+2.5+1+5+6+12+46+3=+10+16 = 135.5 = D

Answer: D

1.2. According to the figure, in the 1980s the number of global deinopid museum collections grew by approximately____________percent.

To answer the second question add the global deinopid museum collections till the year 1970 and then compare it with the year 1980.

Global deinopid museum collections till the year 1970 = 21.5

Global deinopid museum collections till the year 1980 = 21.5 + 12 = 33.5

Percent change \(= \frac{12}{21.5} = 55.81\)% \((33.5-21.5=12 )\)

Answer: D

Sajjad1994

I would like to question the diagram, or at least the correct answer to the second question. Why is the single year 2019 represented by one entire bar in your explanation? For 2019 you have written 16. But doesnt the rightmost bar represent the latest decade from 2010-2019?

2010-2019: 16
2000-2009: 10
1990-1999: 30
1980-1989: 47

So in the 1980's the collection grew by more than 100 %.

Sajjad1994 · Answer

Read the question statement above the diagram, I cannot write year 2020 as the question statement has said that the data is from year 1800 to year 2019.

NikLexx · Answer

Quite an interesting assignment. I had to stretch my brain

Bambi2021 · Answer

Yes, but the bars represents decades and the 1980's is the fourth decade from the right. This number is 46, not 12. During the 1980's the collection grew by 46.

2019-2010 - the rightmost bar
2009-2000 - the second bar from the right
1999-1990 - the third bar from the right
1989-1980 - the fourth bar from the right

RahulJain293 · Answer

Sajjad1994  I had a doubt.. How do I interpret the table?
There is no mention of what does the black bar or the points depict.. Also the 'N Adults' is something that is not explained in the question..

When I need to add something for ex, in Q1 - I am confused if I am to use the black bar as reference or the square points as reference.

Please help advise!

Sajjad1994 · Answer

Growth is depicted by square points and bars are just following them to show the overall growth trend. You don't need to know detail about the N' Adult to answer the question. Some data is always provided to trick or confuse the test takers. Furthermore read my explanation here in the link below. https://gmatclub.com/forum/the-figure-b ... l#p2697968
