Hi, I have a doubt with this type of graphs (pie chat + a bar). My understanding: the bar from the right represents the detail inside Computing. So, if i want to compare Life Sciences and Physical Sciences vs Network/Sys Admin, the final percentage of Network/Sys Admin would be 0.74*0.07. Is my reasoning right?

gmat_grand_master · Answer

If you add all the percentages in the bar you will see that they add up to 74%.

You are correct. The question should have been more specific on what does the column on right represent.

Parthkulkarni · Answer

Hi, Shouldn't the answer for the 1st question be "50% more" and the 2nd question "more than". The reason we cant take the value of SD as 32% is because its 32% of computing which is 74% of stem jobs..
Similar reasoning applies to 2nd question as well. Pls, feel free to correct me if I have misinterpreted the question. Thanks!

KBoss27 · Answer

Parthkulkarni  I have the same understanding and I feel this is the correct approach to this.  chetan2u  - this seems like a poor quality ques. Could you please tag it?

miag · Answer

hi , I also got 50%, and more than with the understanding that the second chart is a breakup of Computing...could you confirm if the given answer is correct?

Hi  KarishmaB , can you please give your 2 cents worth on this question! I feel the same as  Parthkulkarni  and  miag

KarishmaB · Answer

This is a standard pie chart and gives the break up of 74% of Computing in a list. The percentages in the list add up to 74%, not 100% There is no ambiguity here. The point is for you to comprehend the data given hence it is not necessary for the test maker to exactly explain what is going on. 
The answers as given are correct.
