1.1 Total number of current deinopid museum collections = 17+10+30+45+12+5+4+7+5 ~135, Ans. D

1.2 Ans. E = 60%

The histogram shows the decade wise collection and rising curve is cumulative collection.

1.1. According to the figure, the total number of current deinopid museum collections is approximately___________.

A. 100
B. 105
C. 120
D. 135
E. 150

This has to be sum of all the decade wise values from 1800 to 2019.
0+0+0+0+1+0+0+0+1+0+0+2+3+2+1+4+5+12+46+30+10+16 = 133 (closer to 135)

Hence D

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

A. 30
B. 45
C. 50
D. 55
E. 60

The number of global deinopid museum collections in until 1980 = 0+0+0+0+1+0+0+0+1+0+0+2+3+2+1+4+5= 19
The number of global deinopid museum collections in until 1989 = 0+0+0+0+1+0+0+0+1+0+0+2+3+2+1+4+5+12 = 31
Growth in percentage
(31-19)/19 x 100 = 63.15 % closer to 60%

E

1.1. According to the figure, the total number of current deinopid museum collections is approximately___________.

A. 100
B. 105
C. 120
D. 135
E. 150


answer is e)150 , if we add all the adult spiders it becomes (seeing from left side of graph ) it becomes
(from 1840 to 2010 )

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

A. 30
B. 45
C. 50
D. 55
E. 60

as seen from graph on right hand side % increase in 1980 = 60% so answer is e) 60

1.1. According to the figure, the total number of current deinopid museum collections is approximately___________.

Total Growth in:
2019 = 50
2010 = 44
2000 = 40
1990 = 30
Total = 164. No need to calculate further. We can see that the largest no is 150

IMO Option E

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

1980 is fifth bar from right. the growth is between 20-40%

IMO Option A

Question #1.1 is medium level difficult and comparatively easy to identify but question #1.2 is hard to identify but once identified it become very easy. Good job Sumi1010. OA is updated Its D for both of the questions. Points table will be updated soon.

Good Luck for today’s questions

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 %.

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.

Quite an interesting assignment. I had to stretch my brain

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
