Could anyone help me with this question, please? It's from the Big Book, test 10, section 7 #23 - data interpretation set (Data sheet is in the attachment) Question: If the increase in the number of students enrolled from 1950 to 1960 was half the increase from 1960 to 1970, what was the student enrollment in 1950? a) 745 b) 1,340 c) 1,380 d) 1,435 e) 1,545 The right answer is d, but I just can't figure out how to solve it. I would really appreciate it if anyone could explain me this question! Thank you in advance!

Hi Frens I am having real tough time with Data Interpretation(DI) questions in GRE quantative maths. I was referring to barrons DI practice tests and was unable to solve most of them as i couldnt get the idea about the charts and graphs. Barrons doesnt give a clear explanation for DI questions and tactics are also not that good.. Can anyone suggest me any good book or way to practice DI questions and tactics? Any help appreciated. Thanks! Anu
