360 = b+v+g

1) we have b
but no info for g

INSUFFICIENT

2) b= 0.6 (v+g) (ASSUMING THE BOLD PART TO SOME KNOWN VALUE AS ITS NOT CLEAR)
g is unknown

INSUFFICIENT

1) +2)

No info for g

INSUFFICIENT

hence E

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.

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.

Hope it's clear.

thanks a lot.....
indeed it is imp to check the three eqns whether they are distinct before deciding on outcome....
