The GMAT review book is on the 12th edition; this must have been from an earlier edition, but most of the problems haven't changed, and in fact are only one or 2 numbers away from their positions in this video. I suggest doing sets of about 10, and watching these vids with the approx number in mind
Problem 95: She already has 32 towards the 70. So she needs 38 more years of working or age. Divide 38 by 2 (since she is gaining years by getting older and working simultaneously). You get 19 years. 1986 plus 19 years is 2005.

@Boundless0 The Manhattan GMAT website has a downloadable PDF file that shows all of the corresponding 11th edition questions to the 12th edition.

70-32 = 38
38 / 2 = 19
1986 + 19 = 2005
Much easier this way =]

How about this alternative way for Problem 94:
A + E >= 70
x = Number of years she has to work for the company
(32+x) + x >= 70
32 + 2x >= 70
2x >= 38
x = 19
add 19 to 1986 to get 2005
