I have got the whole thing now? The retailer made a profit of N10 after he bought the good for N190. When he borrowed from the bank, he incured an intrest of N3. The man paid N3 out of his N10 gain. He had N7 left. His gain is N7. What if the question says what is his gain percent?

A blend was made from types of tea, X and Y, so that the mixure contains 20% of type X. If the quantity of X is doubled, find the percentage of type X in the new blend, given that; (i) the same quantity of Y was used; (ii) the total quantity of the mixure was unaltered. How can I tackle this?

The man is going to pay an amount of N203 to his bank. The discount given to the man N10. He finally bought the good at N190. The man's gain is N203-N190 = N13. Could this be correct?

I think am ready now. Let's finish what we started.

X = y/0.2 = 2375k = N23.75

A garage owner sell two cars for N300 000 thereby making profit of 20% on the cost price of the second. Find the loss or gain percent on the total cost price. I believe the total selling price = N300 000. My problem is how to get selling price of each of car

Now the term two months credit, means what? Now the term, "two months credit", means what?

Thanks for trying to explain, but let me try to understand it more: I understand this to mean that the retailer bought goods from the manufacturer at the cost of N200. Right? The manufacturer is expecting payment within 2 months or else penalties will apply (but these are not mentioned)[math]\longrightarrow[/math] The retailer bought the goods on credit and he is being giving the grace of two months to pay. If he pays in, before, or within two months, he would be giving a discount of 5%. Right

The problem is that I don't understand the first sentence of the question? What does it mean (1) "that the retailer has an account of N200"? (2) "the manufacturer gives credit or two months credit"?

X = 2375k = N23.75 But why is Y [math]\frac{20}{100}\times{x}[/math]?

Let x be the original price. N4.75 = 475k x- 475k = ? What do I do next?

A retailer has an account for N200.00 from a manufacturer who give two months' credit but only after a cash discount of 5% for prompt payment. The retailer borrows N200.00 from his bank at 9% per annum for two months and pays promptly to secure the cash discount. How much does he gain by this transaction? How do I solve this? I could not solve this because I don't fully understand the problem especially the first sentence.

Okay, we don't know the original price, when the original price was reduce by 20 k it became N4.75. Right?

In a sale, all prices are reduced by 20k in the naira. If an article was reduce by N4.75 k, what was the original price? I don't understand this problem. I think I need help.

As a percentage of turnover, net profit for 1984 was [math]\frac{N12500}{N130000}\times100[/math] = 9.615% approximately.

Ok. Let say his total cost = overheads + cost price of all goods = 13500 + 104000 = N117500 Right? Sales would be cost + profit = 117500 + 12500 = 130000 average sales would be [math]130000\div52[/math] = N2500 Is this right?

Since Selling price = cost price + profit. Total sales would be N104000 + N12500 = N116500. Could this be right? Average weekly sale would be [math]\frac{N116500}{52}[/math]

Am very happy now. Am very very grateful to Mr studiout for all the help you rendered to me in the course dealing with this problem. Am also very sorry for allowing you go through all the suffering of trying to explain to me despite my inability to grasp the concept. Am very happy to annouce that I have googled a formula which I will always rely on anytime problem of this nature comes my way. Let me apply the formula to this problem. A will do the job a days alone. B will do the job b days alone. They will do it together for 15 days. The number of days a and b will do the job together is given as [math]1 \div (\frac{1}{a}+\frac{1}{b}) = 15 days[/math] ... eq (i) since A did days job for 30 days, we have 9/15 = 30/a a = 50 days putting a in eq (i) we get it that B did the job for (150/7) = [math]21\frac{3}{7} [/math]days

Yes, you did. Thank you!

6/15 + 9/15 = 1 6/15 = 6/b + 6/a 9/15 = 30/a 6/b + 6/a + 30/a = 1 where a and b are the work are the number days A and B did the job alone? I believe this equation are okay enough to get whatever number of days B did the job alone?

Could this be the fraction you want me to show? We were told that they did six days work out of 15 days ways. This means it remains 9/15 days work. Thus 9/15 + 6/15 = 1

Am almost giving up on this.

Since they are working at diffrent rates. How do I know, how long it would take B doing 6 days work all alone. If I can compute that, then I would be able to compute how long it would take B to do 15 days work all alone?

How do we know that they working at diffrent rates?

Am assuming that since A can do 6 days work in 20 day, B could as well do 6 days work in 20 days.
