Thank you so much! For some reason I didn't realize that the question is asking about the enrollment in 1950 and was thought that we are to find the enrollment in 1960:shy: Now it's all clear! Thanks again for your reply!

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!
