Whenever you give a fact it looks better and more smart to show where you got the fact so it can be in the first paragraph last paragraph etc anywhere you give facts you should cite your sources so the information is more trusted and looks better . Hope this helps ! (:
Since A, B and C are correct. I think the answer is D. Linguistic grammaticality and content or effective communication are separate matters.
Answer: Profit = Rs 240
Explanation:
The cost price will be:
= 2800 ÷ (100% + 40%)
= 2800 ÷ 140%
= 2800 ÷ 140/100
= 2800 × 100/140
= 2000
Cost price = Rs 2000
Since the article is sold by allowing 20% discount, the sales price will be:
= Rs 2800 - (20% × 2800)
= 2800 - (0.2 × 2800)
= 2800 - 560
= 2240
Selling price = Rs 2240
Therefore, profit = Rs 2240 - Rs 2000 = Rs 240
Eu não falo bem português, então me desculpe se eu cometer um erro. Para o título, eu sempre escrevo "(Título do livro) Relatório de redação".
Sobre o que é o texto da opinião? Talvez eu possa ajudá-lo a escrever :)
