Direction: This exam is to test on your ability to think out solutions to quantitative problems. Read each problem carefully and determine the correct answer from the choices.
I got only 75%, can someone help me how to get the correct answer in numbers 9,10,14,17,18. i need help please. we have our college entrance exam on saturday. tnx
17. A bag of Pig feed will feed 18 pig in 54 days. how long will it feed 12 pig? 18/54 = 12/n then cross multiplication you will get 18n = 648 then multiply each side by 1/18 so you'll get this n = 648/18 then the answer is 36.
sir can i ask your solution on #17th ? im kinda confused. why does the pig feed lasted 54 days with 18 pigs, rather than the lesser? while they both have the same bags of pig feed
you'll use ratio and proportion there right?.. it's like this: 18/54=12/? so cross multiply 12 and 54 then divide it by 18, i know it's kinda hard to believe that the feed lasted less than with 18 pigs but that's how it is.. :))
it is kinda irrational that a supply lasted shorter when the demand become lower.
lets assume a pigfeed bag weighs 1 kg.(for simplicity reasons than logic) to find the rate a pig eat each day. 1kg(feed)/54(days) = 0.0185 kg/day 0.0185 kg/day for 18 pigs. each pig eats 0.0010288 kg/day
yahh hahhah i have the same answer , to think that the number of pigs is lesser than before so therefore the supply will last longer than before so: 18-12=6*54=324/12=81.... as simple as that lol.
In #8, what you need to do is multiply 9hrs to 0.025 kilowatts (25 watts), which would be 0.225kWh. Then multiply 0.225kWh to Php1.5/kWh = Php0.3375. And multiply it again for 30days, so PhP 0.3375*30days= Php 10.125 for 1 month
Gotcha...85% not bad .....its hard but...look I got 85% maybe I'll try to get perfect score next tie.. Favor...pls explain to why 15 is the answer in no.1...headbreaking.....
..check on question number 17.. logically speaking if it took 54 days for 18 pigs to eat a bag of feed how much longer it will took for the 12 pigs.? meaning the answer should be more than 54 days, not 36 days.
Wth. I got 0% all wrong. And the correct answers shown aren't even in the selection wth!? Correct answer for 1 is 653 the selection for mine is ranged only in 10 below. What the hell?
You should use this formula A = P(1 + rt) for simple interest. A = Total Accrued Amount (principal + interest) P = Principal Amount I = Interest Amount r = Rate of Interest per year in decimal; r = R/100 t = Time Period involved in years
653 cannot exist as an annual rate for any bank in the world. It's really huge. If 653 is the rate, then your money is going to be Php 22, 590 from Php 3000.
look I got perfect score..
ReplyDeleteI really suck at math..can you teach me how to solve the problems -_-
Deleteplease teach me how to solve *puppy eyes*
Deletelol. to become proficient in math.. you need to hav a great passion in math subject. You must be fan of a numbers for so how many years.
DeleteI got only 75%, can someone help me how to get the correct answer in numbers 9,10,14,17,18. i need help please. we have our college entrance exam on saturday. tnx
Deletehow do you get the answer..plsss can u send me a step by step answer..
Deleteha? how come? how did you get the answer at no. 18?
Deleteyeah, tell us how you solved #18?? LIAR!
Delete17. A bag of Pig feed will feed 18 pig in 54 days. how long will it feed 12 pig?
Delete18/54 = 12/n then cross multiplication you will get 18n = 648 then multiply each side by 1/18 so you'll get this n = 648/18 then the answer is 36.
Why 36? Are the 18pig consume longer than 12 pig? How it is goes?
DeleteI got 10, 7 wrong then the 3 i did not answer yet.
DeleteMy answer in number 17 is 81days.
Deletehahahaha i think who made this test is a shawol and exostan / kpopper here also / same fandom...
ReplyDeleteyes me!! im shawon, exostan, bana and army!!!
Deletetaemin , key and minho!!
DeleteYeah, that's right, The kpop names made it cool and exciting to solve. It makes my brain works.
DeleteHahahahahha i was so happy and embarrass at the same time what if my proctor is EXO? lels bababababa
Deletehaha 4/20 i hate math
ReplyDeletemy brain going to blast !
i Hate Math ! but I want To Learn
ReplyDelete.. Yup ! me too :)
DeleteWow. A kpop fan made this! Cool. :D
ReplyDelete15/20 whahah :D galling ko !
ReplyDeletebuti kapa -_-
Deletebuti kapa -_-
Delete15/20 whahah :D galling ko !
ReplyDeletewhat is my wrong, what number?????
ReplyDeletecan you show the solution for each problem ??? for us to deeply understand the problem ? or how it becomes like that blabla .......
ReplyDeleteI believe questions number 10, 14 and 18 have no correct answers.
ReplyDeleteJust wanted to post why I think so...
Delete10. Formula for area = pi*r^2 so it is then 3.1416*135(squared) = 57255.66 sq.km
14. Given information is % without specifying what percentage.
18. 28,000 - (8% of 28,000) = 25,760
then 25,760 - (5% of 25760) = 24,472 is the cost of the set.
The faster way though is 100%-8% = 92% so 28,000*.92 = 25760*.95= 24,472 (cost)
So if you got 85%, that might be why :)
I only got 16 out of 20 ! I am really disappointed .I failed to answer 7,8,10 & 18 correctly.
DeleteCan you please show me their solution?
same solution on 10th, 14th and 18th.
Deletesir can i ask your solution on #17th ?
im kinda confused. why does the pig feed lasted 54 days with 18 pigs, rather than the lesser? while they both have the same bags of pig feed
you'll use ratio and proportion there right?.. it's like this: 18/54=12/? so cross multiply 12 and 54 then divide it by 18, i know it's kinda hard to believe that the feed lasted less than with 18 pigs but that's how it is.. :))
Deletei think you get it wrong, ulquiorra.
Deleteit is kinda irrational that a supply lasted shorter when the demand become lower.
lets assume a pigfeed bag weighs 1 kg.(for simplicity reasons than logic)
to find the rate a pig eat each day.
1kg(feed)/54(days) = 0.0185 kg/day
0.0185 kg/day for 18 pigs.
each pig eats 0.0010288 kg/day
so, 12 pigs consumes 0.012345679 kg/day
a 1-kg bag of pigfeed should last 81 days.
Yeah. #17 is really irrational. How could a lesser group consume the food faster? I did the same solution as with Marc.
DeleteLow demand... supply wil last longer
Deleteits simple..
Delete18x54=972
972/12=81
yahh hahhah i have the same answer , to think that the number of pigs is lesser than before so therefore the supply will last longer than before so:
Delete18-12=6*54=324/12=81.... as simple as that lol.

ReplyDeleteguess some questions are kinda vague..
90%
ReplyDelete60% but needed some recall because i've got only stock knowledge by now
ReplyDeleteI just got 35% LOL ðŸ˜‚
ReplyDeleteLol 40% hahaha I know how to solve but I need formula 1st :D
ReplyDeleteShocks I got 60% without using calculator Haha ..
ReplyDeleteI love math but math hate me :(
My nephews tried tutorilas on http://www.msainstitute.com/, and they got high scores on their exams.
ReplyDelete12/20 = 60%
ReplyDeleteNot really good without the calcu though
So sad I got 25%
ReplyDeleteI really hate math,,super
ReplyDelete75%, what a score!
ReplyDeleteThere are some questions that have no answer on the choices. and the given in no.14 is not understandable.
Delete55%
ReplyDeleteI got 60% lol
ReplyDeleteHaha.. 30% its sucks!
ReplyDelete12/20 more practice !
ReplyDelete50%, not bad. hahaha
ReplyDeletekpop fan tho. haha
75%
ReplyDelete16/20
:)
..check on question number 17.. logically speaking if it took 54 days for 18 pigs to eat a bag of feed how much longer it will took for the 12 pigs.? meaning the answer should be more than 54 days, not 36 days.
ReplyDeleteI only got 85% because some items are really really wrong lol.... -.-
ReplyDeletei got the half. oh great
ReplyDeletecan someone please tell me how to get the answer for number 20. Thanks :)
ReplyDeleteJuz get d 50% of 9 days or 9/2= 4.5 or 4 1/2 days
DeleteWorst !!! (20%)huhuðŸ˜
ReplyDeleteWth. I got 0% all wrong. And the correct answers shown aren't even in the selection wth!? Correct answer for 1 is 653 the selection for mine is ranged only in 10 below. What the hell?
ReplyDeleteYou should use this formula A = P(1 + rt) for simple interest.
DeleteA = Total Accrued Amount (principal + interest)
P = Principal Amount
I = Interest Amount
r = Rate of Interest per year in decimal; r = R/100
t = Time Period involved in years
653 cannot exist as an annual rate for any bank in the world. It's really huge. If 653 is the rate, then your money is going to be Php 22, 590 from Php 3000.
DeleteThe correct answer in number 17 should be 81. Since the number of consumers decreased (from 18 to 12), the supply should last longer.
ReplyDeleteInsufficient data in number 14.
