Ok here is d working:

Let x be the cost price; cost price of 6kg = 6X
With 20% of profit margin, SP = 6X x 1.2
This is the price charged for 5kg
SP of 1kg = (6X x 1.2)/5 = 1.44X ie 144% increase, hence 144%-100% = 44%

My rough working though.



No 2:

Given 8a = 9b and ab = 0;
The ratio of these numbers is [a/9]/[b/8]; substituting in the ratio frm the question, u hv a = 9b/8; the ratio then is [9b/72]/[b/8]; dividing both sides by b and multiplyn both sides by 8, you finally hv 72/72 = 1


Hence:
1.) C
2.) C

I want to disagree with the OP concerning the purportedly right answer. In Kentnickole's answer when he was trying to find the unit cost, i.e 1kg, he divided by 5kg saying that's the price charged for 5kg. The question never mentioned 5kg, but 6kg. And we should take into cognizance the difference btw markup and profit margin. I STRONGLY stand by my answer being RIGHT except anyone or the OP can prove otherwise

He divided by $5 not 5kg

@belovedsamex, the 1.2 is gotten from the 20% profit.

Add 20%profit to the initial value then you get 120% of that value. Which is 120/100 = 1.2

Let's assume he bought it at $x per kg, then 6kg = $6x,

20% profit means (120/100) * $6x = $7.2x this is d price he must sell the whole 6kg in order to make 20% profit ($7.2x)


Then you now divide with the price he sold them. $5 per kg which is

$7.2x/$5 = 1.44x showing 0.44 increment when compared to the initial price x per kg.

The question is very trickish though. Let him come n shed more light into it.

Re: Solve These CHEVRON Interview Questions by Kylekent59: 7:24pm On Oct 06, 2014
Solution to 2
8a=9b
ab=0
Let a/b = a/b * (b/a)^2
Since a/b = b/a
Then 8a=9b
8/9 = b/a
= a/9 : b/9
a/9*9/b
a/b * 9/9
=a/b * 1
Since a/b = b/a
Then ans = 9/8

I want believe the text 'giving' is a typo and ought to be spelt as given. That is to say, he was supplied[given] the goods at that price, hence that is the COST price. The next sentence buttresses this point by saying, If he wants to make a profit of 20% NOTE: He hasn't sold the goods yet. Can someone pls explain to me the rationale behind taking the stated sum as the SELLING [and not the COST] price?
I believe if that was the SELLING PRICE, the question would have looked thus: What was mark up on the cost price, if he MADE a profit of 20%? Which is to say he has done the sales already, hence there is a SELLING PRICE. Folks do u see it any other way?

As the OP of this thread i hearby certify him to have the right answer to the question. Let's learn from his solutions.
He is wrong and you are confused.

The question says ratio of a/9 to b/9

He was busy solving ratio of a/9 to b/8

Re: Solve These CHEVRON Interview Questions by Kylekent59: 8:11pm On Oct 06, 2014
For no 1

Margin =20%
5$=1kg
6kg= $30
Margin = (selling price - cost price)/selling price
0.2=(s.p-30)/s.p
0.2 s.p - s.p = -30
-0.8 s.p=-30
S.p=$37.5. While cost price =$30
Markup= (s.p/c.p)-1
=(37.5/30) -1
=0.25. Or 25%

You see what I mean? The question is senseles.
Let me assume your explanation is right and let me solve it that way then;

From the assumed explanation, cost price = 30 dollars. To make a profit of 20%, he will need to sell it at (20/100*30)+ 30 = 36 dollars.
Then this 36 dolls is the selling price as well as the marked price for a 20% profit.

Difference between the MP(SP) and the CP is 36-30 = 6 dolls.

So now, what % of 30 dolls is 6 dolls?

Let the % = X
X/100 * 30 = 6
30x= 600
X=600/30 which still gives us 20%.

What margin are you talking about? I see you referring to the 20%. So, you mean, to get a 20% profit from a cost price of 30dolls, you are going to sell at 37.5 dollars? Your solution is wrong sir.

I appreciate your effort. I mean that with all my heart.
To make a profit of 20%, we say
Profit margin =[selling price-cost]/selling price.
answer you get x 100%

Kindly go to d 1st page to see my working. I don't wanna spam
SELLING PRICE = SP
COST PRICE = CP

PROFIT= SP - CP
To calculate percentage profit, you divide profit by the SELLING PRICE

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%

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
. I am surprise we are having issues regarding question 1. Many of us don't understand what is markup: we re required to find the unit selling price to make a profit margin of 20% on the 6kg, the answer is 20%. Total cost price is 6x5 equals 30, at a profit of 20%, selling price is 30x 1.2=36. Hence unit selling price is 36/6=6 therefore margin is (6-5)/5 *100=20%.The fact is you don't need to calculate that the percentage on total selling price and unit price will be the same, the same factor applies.

Looking at question 2. No answer satisfy both premise: 8a = 9b, and ab = 0. I can solve the question using only the first premise and the answer is 9/8 but this will not satisfy the second premise. To satisfy the second premise, either a or b must be zero then a/b must be zero or undefined.
