Question 329326: The above piechart represents the results of an election on an alien planet. The candidate, Hum, won the election, receiving five times as many votes as Yab. Pip received 30% of all votes. What percentage of votes did Hum receive?
shouldnt need a chart for this....
if pip has 30% that leaves 70% left, 70% divided by 5 is 14 so thats 44% used already which leaves 56% so hum has 56% of the votes correct? but the answers on the paper say
54.70%
55.00%
58.30%
60.20%
Impossible to tell from the data
but u can figure out the answer and it isnt saying to estimate, so the test is flawed?
