I like the second question. Simple algebra! Questions like this are answered from the options given. Option C is the only integer- making it the only possible answer.
Re: Solve These CHEVRON Interview Questions by daxon001(m): 11:00pm On Oct 06, 2014
na so una questions b Chevronmake una dey expect me soon.dose questions were very interesting,easy n hard at d same time!
1.selling price is 6*5=$30.we have 20% as d assumed % profit.cp=?
we apply %gain=(sp-cp)/cp*100
20=(30-cp)/cp*100
cp=30/1.2
=25.
30-25=5
5/25 *100
=20%
2.d ratio will b simplified 2 a/b and solving further,we get 9/8!
OP how far?cool
Ps:dis has bin modified.and i just realised dat dis op has made things complicated by putting questions which have a strong likelihood of errors!
which is correct now.'is giving' or 'is given' cos both respectively depict different things!

NO, MY BRO. Markup no be grammar ooo. JUST GOOGLE the difference btw markup price and profit margin

20/100-20 * 100 = 25%

Mark up is the %age of profit in relation to cost price. Margin is the %age of profit in relation to selling price.

The seller is given 6kg at $5 per kg and you're expected to find the markup if he wants to make a 20% profit (being the margin).


But why is the OP asking a question whose answer he's clueless about

Solve these questions from CHEVRON PLC past aptitude test questions: pls gv details of ur solution to the most acceptable answer.

1. A shopkeeper is giving 6kg of rice at the price of $5 per kg. What should be the markup on the cost price if he wants to make a profit of 20%?

OPTIONS: A. 25% B. 50% C. 44% D. 20%
Without solving I know the answer is 20% (D). But since you want details, here it is:

Cost Price of Rice = $5 × 6 = $30
Therefore Cost Price = CP = $30
Let the Selling Price be designated as SP
Therefore to make a profit of 20%, we have:
(SP - CP)/CP × 100 = 20
(SP - 30)/30 = 0.2
SP - 30 = 6
SP = $36
Therefore Mark-Up = SP- CP = $36 - $30 = $6
Thus % Mark-Up = 6/30 × 100 = 20% (D)

2. If 8a = 9b, and ab = 0. what is the ratio of a/9 to b/9?

OPTIONS: A. 64/81 B. 8/9 C. 1 D. 9/8 E. 81/64
8a = 9b
Divide both sides by 72
8a/72 = 9b/72
a/9 = b/8 .......eqn(1)

Thus to find the ratio of a/9 to b/9 = (a/9) ÷ (b/9).......eqn(2)
Let's replace a/9 with b/8 (substituting eqn 1 into eqn2)
Thus the ratio changes from (a/9) ÷ (b/9) into (b/8.) ÷ (b/9)
This gives 9/8 (D)

Let's not allow the equation ab = 0 confuse us.
This because, it's not possible for only a or b to be equal to zero (as it would contradict the given equation 8a = 9b). Thus BOTH a and b MUST be equal to zero and using it to solve anything would result in 0/0 which could be anything thus is indeterminate.

In conclusion, my answers are

1. D
2. D

Well, bro the truth is,,, mathematics is not like any other subject. even though i couldnt solve the question myself we all know a right procedure wen we see one. and watevr contravaines acceptable mathematical principles we can easily detect. that is why you see all these erudite fellows disputing with different answers.
i put the question up here so that i cud get a clue of how to do the working from whoever knows how to go about it. if i had idea about it why should i post it then? i don't show myself. what i kno i kno and keep to myself or teach whoever needs it, and what i don't kno i try to learn from odas.
dnt be freakd out by the many contradictions. its gud for ppl to express themselves based on what they know. i shudnt begin to fret because some ppl tink dat d question is not well-framed. what about those who feel otherwise. everybody is allowed to express themselves d way they like. if u feel u cant handle it just look and pass.

No o. The question said find the ratio of a/9 to b/9. But you decided to use a/9 to b/8


Given: 8a = 9b and a/9 to b/9
thus a = 9b/8; so substitute 9b/8 into a/9, you hv [9b/8]/(9) = 9b/8 x 1/9 = b/8...

Also, b = 8a/9; so substitute 8a/9 into b/9,
You hv [8a/9]/8 = 8a/9 x 1/8 = a/9...

Place back in the ratio line, you hv:

a/9 to b/8.

Re: Solve These CHEVRON Interview Questions by agabaI23(m): 12:47am On Oct 07, 2014
Instead of the dogo turenchi that is not clear even to the op just get the cost price and multiply by 120 or 1.2
Cost price: 6x$5=$30
$30x1.2=$36
(36-30)/30x100/1= 20% markup
Each kg sells for $6
Which $1 markup per kg
($1/$5)x100= 20 %.

Wrong.

Cross-check the bolded. It should give you 8a/81 and not a/9

Ohh... Thats true. Typo please pardon; I didnt check. In my rough work I left a/9 and then substitute b/9 for b/8 following the a = 9b/8 above for convenient solution...

The answer is 9/8. Look at it critically.

Note that ratio a/9 to b/9 is the same as the ratio a to b (ie a/9 : b/9 = a:b)

Re: Solve These CHEVRON Interview Questions by benrowlyC(m): 1:46am On Oct 07, 2014
Isryl02:
ratio of a/9 to b/9 = a/b which is the inverse of b/a; hence the answer shud be 9/8, check it again
it shuud be 8/9. Cos it simply shud b d inverse of d denominator, thereby bringing all 9's to a canceling effect

WELL, having gone thru the comments i was struck by d fascinating answer given by @KENTKNOKI.
He didnt only gv d CORRECT ANSWERS as C C but also showed a thorough working which i quite ascertain is correct.

As the OP of this thread i hearby certify him to have the right answer to the question. Let's learn from his solutions.

eckersley says;
GOOD. its good you've seen my point. But that's not enough. U have to go back, EDIT UR POST THAT SAYS HIS ANSWER TO THE FIRST QUESTION IS RIGHT AND INVALIDATE IT.


Why are you finding it difficult to MODIFY your previous assertion that Kentknoki got both answers right, despite my quote above that you shd do so?

2ND. Nxt time u post a question you do not have an answer to, do in a HUMBLE MANNER, rather than pontificating about it. "No. you guys are all wrong," I'm still waiting for the right answer, and Kentknoki got it right. Go and learn from him".
You shdn't parade yourself in such a pompous manner next time. Garrit?

Your opinion my dear. But whn u encounter such in an exam or test, dont make wrong choice if u value just a mark.

Bro the bolded is wrong, the 8 in angular bracket is suppose to be 9. Which will give you 8a/81.

The contention is how I came about a/9 and b/8 instead of a/9 and b/9

Now here is the working:

a = 9b/8; substitute in a/9, you hv

9b/8 x1/9 = b/8.

b = 8a/9; substitute in b/8, you hv

8a/9 x 1/8 = a/9.

Am sorry for any mathematical ambiguity. I just checked my earlier rough work. Thanks guys for understanding.
