Quantitative Ability and Data Interpretation Question on Pie Charts
Which of the following can be the minimum number of genetically modified rodents that are hamsters?
A
820
B
880
C
840
D
860
E
800
Answer
860
Explanation
Solution
For the rodents:
Let the number of rodents modified as rats be x.
If the genetically modified hamsters must be the minimum possible.
For Purple eyes:
50 - 35% of x ≥ 0
50 ≥ 0.35x
142.85 ≥ x
If x can be a maximum of 140 (since x must be a multiple of 20), then minimum number of genetically modified hamsters = 1000 - 140 = 860
So, the answer must be option D.
