In a group of 50 people 30 like drinking tea and 20 like drinking coffee. How many people like to drink only coffee, if all 50 people liked at least one of the beverages and 6 people like neither tea nor coffee?
Let’s solve this using a venn diagram.T = TeaC = Coffeen means numbern(T) = 30n(C) = 20Universal = 50n(T U C)' = 6 , T union C complement (people who like to drink neither)Let n(T Π C) i.e. T intersection C (People who like to drink both) = xn(T) + n(C) - n(T Π C) + n(T U C)' = 5030 + 20 - x + 6 = 5056 - x = 50- x = 50 - 56-x = -6x = 6Therefore people who like to drink BOTH Tea and Coffee are 6.People who drink coffee = 20Thus, People who ONLY drink coffee = 20 - 6 = 14 peopleI've attached an image with diagram below for better understanding.
Can someone please answer these!!!?
Get a ruler in your hands. Measure things until you start to understand how a ruler works. Measure some stuff and figure out where the center is. Say you measure a book and it's 7/8" thick. You look at your ruler and see that every eighth is divided into two sixteenths, so obviously half of 7/8" is going to be 7/16". If you write that out you have 1/2 x 7/8 = 7/16. And you notice that 1/2 is divided into 2/4 and then into 4/8 and so on, so you can convert anything to anything by multiplying all the numbers on top and then all the numbers on bottom. Other rulers are divided into 10 and 100 parts. But an inch is still and inch, so anything on one ruler can be translated to the other ruler. A half inch on one ruler is 5/10 or 50/100 on the other. An eighth inch is just 12.5 marks when you have 100 marks per inch. A metric ruler divides an inch into 25.4 parts, so a half inch would be 12.7 of those parts. Pretty simple, isn't it? Practice this a bit and people will think you went to wizard school. Percent is simply a ruler with 100 marks. In #1 you are given that 100 marks are worth 30 shots, so each mark is worth 0.3 shot and 65 marks are worth 19.5 shots. The other questions only involve counting. #5 involves conversion factors. A conversion factor is a fraction equal to 1. You know that 60min = 1hr and you can write that as 60min/hr = 1 or hr/60min = 1 whichever works for you. So you write on the left side "ANSWER =" and draw a long fraction bar. That makes it look like you know what you are doing and gives you time to figure out what to do next. ANSWER = I don't put a fraction bar here because I can't type the problem that way. Start with you given information that you want to convert. Then add conversion factors as you need them. Notice that I included the units in the factors. That is because units are part of the fractions and they have to cancel, leaving only the unit you want at the end. ANSWER = 150 people/min x 60min/hr = 9000 people/hr 9000 people/hr x 24hr/day = 216000 people/day 216000 people/day x 365.25day/yr = 78,894,000 people/yr Ordinarily you would only need one answer, so you multiply all the numbers on top and then divide by all the numbers on bottom.
What advice would a 70 or 80 year old person give about the way the life should be lived?
If I may, I would like to add to what Dan Maloney wrote, especially regarding his advice to “Act happy.”My father acted happy throughout his life. He had many friends, and he lived just past the age of 90. Not only did he act happy, he went out of his way to help others, including being a Boy Scout Leader for many years. I tend to take after him, almost always with a smile on my face, and I would certainly say that my life has been blessed with good fortune overall, with a few potholes along the way for contrast.I’ve endeavored to set a good example for those closest to me—especially my children, and on several occasions I’ve attempted to understand, and even explain, why acting happy works. Prior to the study of the wisdom of Kabbalah, the best explanation I could come up with was the concept of fate called Karma, as in: “What goes around comes around.Now, I know that acting is serious business because it’s a law of nature, i.e., a force that operates much like the force of gravity. (We may not understand it, but it’s always there.) The habit of acting in a certain way becomes second nature, until we’re unable to act any other way because it brings us pleasure.If you combine acting happy with acting favorably toward others—for example, by not spreading negatives about others as Dan mentions, then you have a winning “recipe” for happiness. This is because the sensation of happiness emerges as a result of feeling that you’re in a correct social environment, i.e., a supportive and balanced one.Hopefully, I’ve whetted your appetite to explore this matter more, as it is indeed a way to influence your fate.

Are 60-year-olds sexually attracted primarily to people their own age, or do they still find people in their 20s-30s to be the most attractive?
Yes and No. (This question cannot be answered with a "Yes" or "No" as phrased).Yes, I'm primarily sexually attracted to people in my age group. Do I find all of them attractive? No, but some make my knees week. My spouse makes my knees weak whenever we lock eyes.No, I don't find people in their 20s/30s to be the most attractive. Do I find some of them attractive? Yes indeed. Some make my knees weak. Some of ANY age group will just not be attractive to me. Those who smoke or otherwise don't take care of themselves, and those who obsess over relationships pasts and nuances of delayed text responses on Quora make me roll my eyes, sigh, and pound my hands on the table in disgust. No amount of mature elegance or supple, perky body parts can overcome this feeling. I've been entranced by a couple in their 20s and 30s, though typically they have been those were wicked smart and could hold up their end of a conversation.They held my mind entranced long enough to forget they could, technically, be my grandkid. And then the bubble pops; but my knees may remain weak. Heck, my knees are always weak because I'm old, anyway. I don't know where Quorans get the idea that people over 60 are sexless, lifeless zombies who spend their days groveling in misery because they have sagging body parts and wrinkles around their eyes and buttocks and because they just can't understand computers. And sex may not be something we obsess about quite as much as when we were younger, but the sex drive still exists and is still quite passionate. And the sex is often much more rewarding than what I had when I was younger.Some may fit the stereotype, but most of the ones I know don't. Most I know are sexually active, they don't bullshit around in relationships, know what they want, and won't tolerate crap from their partners. They will usually get directly to the point (life IS short!!!) and may stay just away from technology because they prefer direct interaction to hours of inane Tinder-swiping and Facebook-like obsessing (life IS short!!!) And remember, not everyone UNDER 60 leads a life of satisfying sexual prowess with intellectually interesting partners with the sculpted, glistening bodies of gods and goddesses. There were quite a few years where I didn't take care of myself -- I'm in much better shape now, mentally and physically, and find myself much more satisfied in all aspects of my life.
Do old people have sex?
Sure they do. Look at some movie/ music stars who are having babies late into their age with a younger partner. Don't give me the "fresh outta the turkey baster" reply. Male: Viagra, and other products can chemically enhance the function of the male organ, per se. While there are other methods of aiding the male gender with surgical implants, pumps, etc. And last but not least, lets not forget the fortunate gentlemen who have no trouble at all doing what they do in the bedroom. Female: Of course there is the odd question whether the appetite still presents after menopause. I would say that it varies. Some women experience a lack of natural lubricant after menopause, which can be easily remedied with over the counter gels and lotions for the intended purpose. Other women claim a lack of interest, whether this relates to the above statement or not , depends certainly on the individual, their level of confidence in their partner, and their own personal understanding and comfort with their aging body. Lets not forget- the viagra for the lady- is well on it's way if not out allready. So, now lets talk about something else. You say it sounds pretty gross that people over 60 may or may not have intercourse. Well, let me pose an extended question to you in return. Do you think that say boys/girls in hs are attractive, or in gradeschool, or in college, or as married couple with children? Whichever portion of the question applies to you is what you are presently attracted to . Now consider yourself 40 years older , and pose the same question again. You will find that the attractive agegroup as significantly shifted , or at least so it does for most people. In conclusion, if ya like it , and you have a way, why not enjoy what brings you pleasure, even if you are over the age of 60. * *Illegal substance, behavior, and methods are hereby excluded in the above statement
Do you ever wonder what life will be like in 20 years?
I always wonder what the trends and culture will be like in 20 years, in 2030. You know like how the 60's was different from the 70's and so on. I wonder how everyone will dress, what type of music will be popular, what type of president we will have, everything. What do you think? Also how old will you be in 20 years? I'll be 40...damn
