If a certain charity collected a total of 360 books, videos, and board games, how many videos did the charity collect?
(1) The number of books that the charity collected was 40 percent of the total number of books, videos, and board games that the charity collected.
(2) The number of books that charity collected was 66 32 percent of the total number of videos and board games that charity collected.

we get two equations using two statemnets .so we will be able to get value of v and g right?
Statement 1 tells us of the 360 books, videos, and board games, 144 were books. (360 b v g * .4 books = 140 books) That leaves 216 videos and board games. Insufficient.
Statement 2 states of that the number of books is 66.32% of the total number of videos and board games, in this case 216 * .6623 = just under 144, but for our purposes 144 books. Insufficient.
1 + 2: 360 = 144 books + 216 videos and board games. We don't have enough information to tell us how many of the 216 remaining items are videos or board games. _________________

could some instructor please explain:-
three equations have been formed-
1. from question stem. B+V+G =360 2. from statement 1. B= 144 NOT SUFF ALONE 3. from statement 2. B= .66( V+G) NOT SUFF ALONE
Now, i just saw 3 equations , and 3 variables. and proceeded that with 3 equations 3 variables can be found and , therefore , chose 'C' as the answer. Why did it go wrong?

pl help with the explanation.....
The point is that we don't have 3 distinct equations: the third equation is the same as the second one.
If a certain charity collected a total of 360 books, videos, and board games, how many videos did the charity collect?
Given: B + V + G = 360.
(1) The number of books that the charity collected was 40 percent of the total number of books, videos, and board games that the charity collected --> B = 2/5*360 --> B = 144. Not sufficient.
(2) The number of books that charity collected was 66 2/3 percent of the total number of videos and board games that charity collected --> B = 2/3*(V + G) --> B = 2/3*(360 - B) --> B = 144. Not sufficient.
(1)+(2) We only know that B = 144 and B + V + G = 360 (V + G = 216) --> we cannot solve for V. Not sufficient.
