Why do Africans always refer to European mathematicians, scientists or engineers when we have had plenty of great scientists like Imhotep. Did you know Europeans came to Africa to learn?

i dont like maths but i love counting money when its mine

kobonaire: Let's say Kelly initially had x Naira. So if she too 20% then
Money taken to market : 0.2x
Money left at home : 0.8x

Radio initial listing price was 25% higher than what she took to the market which means
1.25 * 0.2x= 0.25x

Seller adjusted price was 50% of what she had left at home => 0.5*0.8x= 0.4x
And this price is a 14 2/7% markup of what it actually should have listed for => 1.1427 of what it should have listed for. (The question becomes ambiguous here IMHO).

Anyway if the original price is y then the mark up price is 1.1427y and since it is equal to 50% of what she left at home=>
1.1427y=0.4x

The difference between the original price and initial price is what percent of total money Kelly had?
Original price = 0.4x , initial price = 0.25x => difference - (0.4-0.25)x = 0.15x and as a percentage of what Kelly had = 0.15x/x = 0.15 (15%)

What percent of the profit is the mark-up price? Isn't this simply the mark up? I don't get the question, please clarify @paranorman

U r a very good mathematician its nice 2 meet u. Buh let's look @ it dis way 'wen it comes in fraction form, solve it in fraction form 2 make it clear'
Let 'k' b d total amount
She took 20%k 2 d market
Initial radio price on d manufacter's list is 20%k +(25% of 20%k) = 1/4k = 25%k
Original price 50% of 80%k = 2/5k = 40%k
Now d diff btw original and initial = 40%k - 25%k = 15%k
And mark-up % = (originalprice - initial)/initial
= (40%k - 25%k) /25%k
= 15%k / 25%k
= 3/5%
Note: 14 whole 2/7 % is d same as 100/7 %

GOOD MORNING TO EVERY PEACE LOVING NIGERIAN OVER HERE

Be sure u dat u wil do d solving if no one is able

paranorman: Out of the total money on her, Kelly took 20% off with her and left over the rest at home on her way to the market. On getting to the market, she saw a radio she liked but found out its price (initial) on its manufacturer's list was 25% higher than what she took to the market. So she thought she could work something out with the seller but was disappointed when told the list got old, prices were adjusted due to inflation and the radio could only be sold at a price which was 50% of her left-over at home; this price was a mark-up of 14 whole and 2/7 % on the original price the seller should have sold it and make a decent profit.

The difference between the original price and initial price is what percent of total money Kelly had?

What percent of the profit is the mark-up price?

my teacher no remember teach me this one

Didn't even know someone posted this. But exactly what I did. 1st part iڪ too simple. 15%. I guess even the second part iڪ also simple only if you make your question clearer. Either you or I must be missing out something in it @op

This is the only person that got it right. Even the OP got it wrong.
Answer 1: 10%
Answer 2: 33.33%

Tinkybabe: Let's assume she left home with t(20% of total money)
She left at home 4t (80% of total money )
and In total had 5t

Initial price of radio= (0.25t + t)= 1.25t= 5/4t
Final price = 50%(4t) = 2t
Original (should have been) price = y =7/4t


2t= y+(100/7%)y
2t= y+1/7y= 8/7y

Hence y = 2t(7/8 )= 7/4t

Now we have a uniform variable

1) difference btw original and initial price as a percentage of total money

Ie (7/4 -5/4 )t = 1/2t or 0.5t

% of total money = (0.5/5)100= 10%



2) what percent of the profit is the mark up price?

Total profit made = final price -initial price
ie. 2t - 5/4t = 3/4t

Mark up price = (100/7)% of y = (1/7)7/4t = 1/4t

(Recall y = 7/4t from above)

Percentage profit in mark up price =
(1/4 divided by 3/4)100
(0.25/0.75)100

= 33.33%**

PS-
Op..the second question is ambiguous- do you mean profit made from original price or final price?
I assumed profit from final price though.

thanks for your nice words.
Your explanation to the problem was very clear and lucid. I think the OP should recognize your solution .... you are no doubt Mr Mathematics

Thingz like this is necessary at times just to re awaken the brain and keep it lighted up.

MATHS !!!

hassymo5: I hate maths bring something on BIOLOGY
....

You can post it. Dr(s) are flenty here

Let the money she has be denoted by: x
She took out:20%of x =x/5
Left at home is x-(x/5) =4x/5
Initial price of radio is:25% more than 20% of x=6x/25
Original price is 50% of money left at home=2x/5
Difference between money left at home and initial price=(2x/5) - (6x/25)
=4x/25

Profit made by the man selling radio =142/7%=100/7% of (2x/5)
=1/7 *2x/5
=2x/35

NwaNimo1: she for carry credit card to prevent all dis calculations,

1st answer is 15%.
2nd answer loading.....

Initial is 45%
marked price =40%
i try sha.......8-)

Tinkybabe: Let's assume she left home with t(20% of total money)
She left at home 4t (80% of total money )
and In total had 5t
Initial price of radio= (0.25t + t)= 1.25t= 5/4t
Final price = 50%(4t) = 2t
Original (should have been) price = y =7/4t

2t= y+(100/7%)y
2t= y+1/7y= 8/7y
Hence y = 2t(7/8 )= 7/4t
Now we have a uniform variable
1) difference btw original and initial price as a percentage of total money
Ie (7/4 -5/4 )t = 1/2t or 0.5t
% of total money = (0.5/5)100= 10%

2) what percent of the profit is the mark up price?
Total profit made = final price -initial price
ie. 2t - 5/4t = 3/4t
Mark up price = (100/7)% of y = (1/7)7/4t = 1/4t
(Recall y = 7/4t from above)
Percentage profit in mark up price =
(1/4 divided by 3/4)100
(0.25/0.75)100
= 33.33%**
PS-
Op..the second question is ambiguous- do you mean profit made from original price or final price?
I assumed profit from final price though.

Q1- I agree it's 10%
Q2- The question says what % of the profit is the markup price?

There is a difference btw "markup" and "markup price".
*markup--- is the 14 whole 2/7% increase of the original price.
*markup price---- is the original price + markup.

According to the info you already provided,
Markup price= 2t.
Profit =3/4t.

Ans= 2/(3/4) in %.
=2.667 *100
=266.7%approx.
* By the way, you're very good, your method is simple and straightforward.

1) 10%
2) Profit = markup = 10/10*100 =100%

CarlOzeki: The easiest and quickest way to solve the question is to pick a number

Assume Kelly had #100.
She leaves home with 20% of that (#20) and leaves #80 at home.

The manufacturers list price is 25% higher than her #20. This is 125% or 1.25 x 20 which is #25 (Manufacturer List price)

The inflation adjusted price is 50% of what she left at home. This is 50% or 0.5 x 80 which is #40 (Inflation adjusted price)

The inflation adjusted price represents a 14 2/7% mark up on the original price. 14 2/7 is 100/7%. Since it's a markup, the inflation price is (100 + {100/7})% of the original price. This is 800/7%. Changing that to fraction is 8/7. Hence, 8/7 x original price = Inflation adjusted price = #40.
Original price = 40 x 7/8 = #35

We have all the prices now.

1. Difference between original price and initial/manufacturer price = 35 - 25 = 10
10/100 = 0.1
The answer to the first question is 10% if considering her total #100 or 12.5% if considering only the money she left at home.

2. This question makes no sense because the item has not actually been sold so there can't be any profit.
If you assume the profit from selling at the markup price of #40 and also assuming that the cost price is the manufacturer list price of #25, then the: profit is #15. Hence the markup price percentage of the profit is 40/15 = 266.7%

You're very correct bro, the first question is however considering the whole amount she had initially, so the ans is 10%.
