How come this can not be solved by B??
Hi.. This question can be solved using sets. According to this question I need to know terms common in A,B,C i.e the intersection. With Fact statement 1, I know out of 16 terms 9 are common to C. So its sufficient because I can find A intersection B intersection C value as 9. With Fact statement 2, I know the intersection of A and B, B and C, A and B. I also know A, B, C. Here because I do not know only A, only B and only C I can not find out what is A intersection B intersection C. Moreover I do not know what is the total number of terms (i.e. AUBUC). So Not sufficient. Answer will be A P.S. Draw the diagram for sets. It will be visually clear.
1.While Mel is on disability leave, his employer pays him a monthly disability benefit equal to $1,200 plus 40 percent of the amount of his monthly salary in excess of $2,000. What is Mels monthly salary?

2. If car X followed car Y across a certain bridge that is 1/2 mile long, how many seconds did it take car X to travel across the bridge? (1) Car X drove onto the bridge exactly 3 seconds after car Y drove onto the bridge and drove off the bridge exactly 2 seconds after car Y drove off the bridge. (2) Car Y traveled across the bridge at a constant speed of 30 miles per hour.
3. What is the maximum number of rectangular blocks, each with dimensions 12 centimeters by 6 centimeters by 4 centimeters, that will fit inside rectangular box X?

To start with: Let m = number of men w = number of women thus, m + w = 1400 rephrase question to "what is w?"
statement 1: 0.36m + 0.5w = 0.42(1400) SUFFICIENT, from the beginning we have m + w = 1400, we have a systems of equations so we can solve for unique values of m and w. SUFFICIENT:
note: because the number of men = 1400 - number of women, you could also rewrite 0.36m + 0.5w = 0.42(1400) as 0.36(1400-w) +0.5w = 0.42(1400) one equation, one variable, solve for w.
Statement 2: we are told that the number of men who support engineering is 288. we can calculate the number of women who support engineering but we dont know the numbers of men and/or women who do not support engineering. INSUFFICIENT.

A group of men and women gathered to compete in a marathon. Before the competition, each competitor was weighed and the average weight of the female competitors was found to be 120 lbs. What percentage of the competitors were women? (1) The average weight of the men was 150 lb. (2) The average weight of the entire group was twice as close to the average weight of the men as it was to the average weight of the women.
Does the integer k have at least three different positive prime factors?
1) k/15 is an integer
2) k/10 is an integer
1) as k is a multiple of 15 so 3 and 5 must be its factors... but we dont know about other prime factors.. so insufficient 2) as k is a multiple of 10 so 2 and 5 must be its factors...but we dont knoe more...so insufficient Combine the... k is a multiple of atleast 2,3,5 so it will definitely have atleast 3 prime factors.. so by combining bothe the statements we can answer this one....

The answer is obtained by using both the satements together.... what is the OA??
Im answering the GMAT on the third of February and have given three practice tests so far. My scores have been 650, 690 and 700 , in that order.
I noticed that i seem to be getting mostly data sufficiency questions wrong. For example, in one of tests out of 37 quant questions, i got 12 wrong of which 8 were DS questions.
Can someone help me here with any strategy or do you just recommend practice, practice and more practice?
Hope someone can help me out soon as i need to consolidate my prep in these next two weeks.
hey puys can anybody give the answer for this data sufficiency question
A)1 alone is sufficient to answer the questions B)2 alone is sufficient to answer the questions C) both 1 and 2 together are required to answer the question but neither of the two is sufficient to answer the question D)either 1 or 2 alone is sufficient to answer the questions E)neither 1 nor 2 is necessary to answer the question
given below is an equation where the letters represent digits
