2. Sale of 20 articles at a gain of 16%= 116% : 20*116/100= 23.2% actual gain Sale of 10 articles at a loss of 6%= 96% :10*96/100= 9.6% actual gain p/l= 100-(23.2+9.6) p/l= 100-32.8 loss= 67.2%....in my own sha |
mathefaro: 1. A Gp of a positive terms and a Ap have same first term.the sum of their first terms is 3 the sum of their second term is 3/2, and the sum of their third term is 6.find the sum of their fifth termschoi, Let's Go There (LGT)... 1 first term: a+a=3 a= 3/2 second term: ar+a+d= 3/2 ar+a= 3/2 - d multiplyn thru by 2: 2a (r+1)= 3-2d but a= 3/2; simplifyn gives: 3+3r= 3 - 2d 3r= -2d d= -3r/2..... 3rd term gives: a+2d+ar2= 6 simplifyn givs. . . a(1+r2)= 6-2d giving 3/2(1+r2)= 6-2d reduce by multiplyn thru by 2. . . 3r2= 9 - 4d but d= -3r/2 substitutn givs 3r2-6r-9=0 r2 - 2r - 3=0 r=3 or -1....but r=3 since term r is positive, hence a=3/2, r=3 and d=-9/2 hence d sum of their 5th term; ==> a+4d+ar4= 122 courtesy My Oga At The Top; Sir Onioshine |
Michael Sokoto: The guy blast naa! Or wat do ya expect?hmmm. . . .if Dibu's only legitimate son could upgrade scores, who am I to downgrade ![]() |
@2nioshine, thanks for shedding light and to all maths-gurus in the house i'm grateful as well. |
Michael Sokoto: The guy BLAST naa!lolz. . . .u foni die u b Dibu first and last son |
[quote author=oladoya][/quote]@oladoya you're also welcome on board. Was given 209. . .God help us and crown our efforts with success |
Amen! Bro, that's the token, I also really appreciate |
Afritop: I HAVE MODIFIED THE QUESTION IN MOBILE AND DECIMAL FORM. So the time he takes for the double journey is 6.25hrs OR 6 WHOLE NUMBER 1 OVER 4. The question is from new general mathematics SS1 EDITION on exercise 6D QUESTION 18Oh! Oh!! Oh!!! Now I get you bro. I thought you meant for each of the journey he cycled at different speeds the same time of 6 1/4hrs or 6hrs 15mins. . . Let the distance be x since we're looking for the distance covered. . Time taken for both journeys= d/s + d/s 6 1/4= x/18 + x/12 L.C.M is 216 and 6 1/4 is 25/4: 25/4= 12x + 18x/216: Cross multiply; it bcoms: 48x + 72x =5,400 120x=5,400 x = 45 Therefore the total distance covered = 2(x) 2(45) = 90km To check: 45/18 + 45/12 = 2.5 + 3.75 = 6.25 or 6 1/4. . . .That is the time taken at 18km/h is 2.5hrs and at 12km/h is 3.75hrs |
^^ Amen |

Ajani2010: i check my question paper after d exam...all i could think of is above 280 but now i scored 229...but accordin 2 last yr cut off i av 2 score 70+ in putmeYes bruv, also thought alike. I did last year; scored 65 in p-utme, 235 in jamb and aggregatd 61.88. The merit cut-off was 68.13 and for my catchment Ogun was 63.50, 1.63 marks difference. If I had known I would have claimed Lagos 59.75. . . |
zhukafa: No wahala, am here to assist peopleok na, no shaking! Keep it up bruv, you're blessed. . |
Ajani2010: whats ur scoreI wasn't scored, I was only given a score as low as 209. You're 2.5 marks ahead of me in the first division. |
Ajani2010: @houz my jamb score is 229...am i good 2 go 4 economicsSo you're my course mate? Welcome on board sire. . . |
Afritop: QUESTION: A man cycles to a village at 18km per hour and returns at 12 Km per hour. If he takes 6¼ hours for the double journey, how far does he ride altogether?Bro the question itself contradicts. As in how can one journey at different km/h but destinates at the same time? Wetin im dey do for road wey im speed at 12km/h and still got there in 6hrs 15 mins, abi e branch canteen? |
@doubleDx thanks, you're so nice |
zhukafa: NDESI SAMUEL SEMACOThanks jare, you're too nice. . . |
Original folks, plz help me re-check for this dude 36580848FF |
^^ @Doubledx Plz i came across this challenge in one of the threads: 1. A GP of a positive terms and an AP have same first term. The sum of their first term is 3, the sum of their second term is 3/2, and the sum of their third term is 6. Find the sum of their fifth term. 2. A trader bought 30 articles, he sold 20 of them at a gain of 16% and sold the remainder at a loss of 4%. Find the percentage profit/loss on the articles. 3. Find the value of x if (x+3)^3 + (x+4)^3=(2x+7)^3 Guyz do something. . . |
johnpaul1101: goodday every1, plz i need help here:In base seven sire I salute una oo. . . .me never reach 'A' level lyk my ogaz coz i'm still an aspirant |
acidtalk: What in Heaven's name is This Country Nigeria turning into?Permit me or not, you're the biggest fool in the world and a cold blooded schadenfreude!! In fact you're a disappointment. Everyone is persuading the board to make amends of its errors, u dey there dey talk 4rm ur yansh old fò*ól. . . |
Fynestboi: atleast wat i wrote up deir ve nt gotten into gettng such sass write up 4rm HIM.. He really disapoint me and he said he"s a graduate.. ¤smh¤You guyz should please take it easy, we shouldn't go about with chips on our shoulders let's behave maturely please. |
^^ But ma'am you shouldn't have taken offence at fynestboi's seeminly innocuous comments cause this very particular isn't far from the truth. Though he might be of an obnoxious nature he's only trying to make this one more clear but terse. . .one love. |
Fynestboi is 101% right oo. . . JAMB itself hasn't announce its official cut-off marks talk-less of other autonomous institutions. The Jamb cut-off you guyz are spreading all over is last year's. So, don't be surprised to see these fed. Unis that don't put theirs below 200 do so this year. |
lockedOut: You can not see your result because you do not have biometric verificationThanks you sire |
Original folks, pls help me check for this bruv 36580848FF thanks! |
phtemie: Lol..Why are you guys so bitter and resentful in your replies?..lol..it is a bitter truth,those who got higher marks performed better...no need to involve the brilliant dudes that got 300+....and about the marking,there was nothing dubious about it...it was just strict...u can criticise me again...fabeg go siddon 4 bush jor |
simdam500: bolded part gbam!!! if 100marks were deducted, defintely those that had 300+ had over 400 right |
simdam500: bolded part gbam!!! if 100marks were deducted, defintely those that had 300+ had over 400 rightGuy, it's totally not as you think. Those that scored 300 and above were given their right score as per centre performance and conduct. A centre where there was a lower case of malpractise tends scripts to be marked and awarded accordinly while a centre where there was high or higher malpractise tends scripts to be marked with a negative or deducting guide thereby making results awarded the other way. So, the guyz who scored these were lucky and had a good centre. Most centres were guilty of this and affected the evaluation of the innocents. |
professor_maths: My fellow aspirants, I scored 263 in jamb , someone said its the highest so far, and I chose lagGuy, you sef dey convinced sey na positive outcome e go be in the long run |
Choi, u guyz dat scored the likes of 100, 101, 123. . . .make una still thank God oo sey JAMB no yeye una competency wit 05 as agg. Imagine, a guy fainted in a cyber cafè when he saw his result to be: Use of Eng= 0 Chemistry= 0 Physics= 05 Maths= 0 Aggregate= 05 I pity the poor guy cause what can he do with that. Oh, no wonder the board gave an interval of 1-159 in its statistics!! My God and my Lord, what's the fate of this dude? What univ'll accept his given score? Does the univ of B-K-H-R-M exists that would grant him admissn to the dept of EXPLOSIVES and FIRE-CRACKERS ![]() So much Pity the guy. I think Jamb was lazy this year and bought random scorer machines and sold the existing ones to FIFA |
ola_pluto: You've stayed on this topic all day trying to justify your failure. If you were sensible, you would have started looking for past papers, remove yourself from nairaland and start solving those past papers.You're a person! Gerraway with your stoic ethics. So you don't want us to protest against the scam jamb did this year and smile that the board indeed has done the right evaluation? No wonder people like you are in support of injustice and unfair treatment. COLD BLOODED SCHADENFREUDIST!!! |
