Hi guys,
i seem to be getting a good grip on Problem solving. but when it comes to data sufficiency i to lag behind.
one of the dilemmas i face is that i am not able assess if the statements are to be believed just as is or there is something more to it. lets me show you example:
Example 1: From Kaplan comprehensive program 2009, pg 302, q 18
Q1. At Consolidated foundries, for a resolution to become policy, a quorum of at least hanlf the 20 directors must pass the resolution by at least a two-thirds majority. At a meeting of the board of directors, did resolution X pass or fail?
(1) Ten directors voted for the resolution.
(2) Seven directors voted against the resolution
My answer was E . . . . but OA is B
its very easy to understand why the answers is B. But let me share how my mind interpreted it, which made me answer wrong!!
My solution: 2/3 of half of directors is > 2/3* 10 = 7 round off. Till here its fine. . . . now statement B says that 7 directors voted against resolution. . . but it does not talk of how many directors voted. May be only 7 voted and those 7 passed the resolution; but this does not meet with the condition that 10 should vote and 7 of them should pass the resolution . . .am i thinking too much!!!
Example 2: From Kaplan comprehensive program 2009, pg 313, q 47
Q2. At the beginning of last year, a car dealership had 150 cars in stock which the dealership had purchased for $20,000 each. During the same year, the dealership made only one purchase of cars. what is the total amount spent by the dealership on the cars it had in the end pf last year?
(1) Last year the dealership purchased 50 cars for $18,000 each.
(2) Last year the total revenue from the sale of cars was $180,000
My answer was A. . . OA is E
again its very easy to understand why the answers is B. But let me share how my mind interpreted it, which made me answer wrong!! as per OA explanation says there is no way to calculate how many cars sold.
My Solution: The dealership had opening stock of 150 cars @ $20000 each. as per statement 1, it bought 50 Cars @ $18,000 each. so we can simple add the value of old stock + new purchase and know the total values of stock at the end of year. . . where is it saying that dealership has to sell something in the year. it could probably not make any sale and be left with stock, value of which is easy to calculate.

. . . guys! pls advise. . .am i insane in thinking so!!
