the answer is surprisingly A
Can’t see why. Neither mathematically nor logically. What is the source?

60

Out of 10 people, 1 couple is sure, so 2 places gone 8 remaing.
Out if 8 , 4 men and 4 women.
If we select one women, we cant select her husband so we can select remaing 3 men. Likewise for every ither women we can sect ither 3 men.
So 3+3+3+3 = 12 ways.
Now one couple we selected at start can be any couple from 5 couple.
So total combinations are 5*12=60 ways

Hello can anyone help with this question? I hesitated between tuesday and wednesday so I’m not sure A particular wall calendar displays the number of the day of the year and the number of days remaining in
the year. If the calendar shows **1/364** for **Monday, January 1**, on what day of the week does the
calendar show **100/265**?

Interesting question! This seems a rip off the GMAT Prep question so I am wondering which prep organization ripped it off 😂 https://gmatclub.com/forum/a-certain-de ... 21113.html

1. This question is discussed here: https://gmatclub.com/forum/is-the-posit ... 06539.html

2. Pure algebraic questions are no longer a part of the DS syllabus of the GMAT.

DS questions in GMAT Focus encompass various types of word problems, such as:

  • Word Problems
  • Work Problems
  • Distance Problems
  • Mixture Problems
  • Percent and Interest Problems
  • Overlapping Sets Problems
  • Statistics Problems
  • Combination and Probability Problems

While these questions may involve or necessitate knowledge of algebra, arithmetic, inequalities, etc., they will always be presented in the form of word problems. You won’t encounter pure "algebra" questions like, "Is x > y?" or "A positive integer n has two prime factors..."

Check GMAT Syllabus for Focus Edition

You can also visit the Data Sufficiency forum and filter questions by OG 2024-2025, GMAT Prep (Focus), and Data Insights Review 2024-2025 sources to see the types of questions currently tested on the GMAT.

So, you can ignore this question.

Hope it helps.­

Easy you can opt for two methods - Hierarchical chart or venn table. 200 cats 70 Street and 130Domestic then 30 Street cats gray and (110-30=80) domestic grey cats and finally if 80 are gray cats then remaining are non gray cats ie, (130-80)cats so the answer is 50

This question is discussed here: there-are-20 ... 20483.html
Hope it helps.
@mhir: This question is slightly different from the question you’ve posted. This says 30 are NOT domestic whereas the one you posted says 30 ARE domestic.

Which should also mean that that there are 200-70=130 domestic cats....and 30 are domestic....so 130-30 = 100 of them are Domestic but not grey

*30 are grey
   1  ...  330   331   332   333   334  ...  353
