Answer 1

$\huge\maltese\color{red}\underline{Answer↓}$

0.5% profit

Explanation:

$\huge\color{red}\underline{Given,}$

Cost of two computers = $1800 each

Gain at S.P. of one computer = 5%

Loss at S.P. of other computer = 4%

$\huge\color{red}\underline{To \:find,}$

Overall gain or loss percent.

$\huge\color{red}\underline{Procedure,}$

First, we need to find the total cost of both the computers altogether.

$1800 + 1800 = 3600$

Now, we need to find S.P. of both the computers

Let one computer be represented by a and other be b

$sp \: of \: computer \: a = \frac{100 + 5}{100} \times 1800$

$= \frac{105}{100} \times 1800$

$= \frac{105 \times 1800}{100}$

$= \frac{189000}{100}$

$= 1890$

So, Selling Price of computer a = $1890

$sp \: of \: computer \: b = \frac{100 - 4}{100} \times 1800$

$= \frac{96}{100} \times 1800$

$= \frac{172800}{100}$

$= 1728$

So, cost of computer b = $1728

Now, we need to find the sum of the S.P.s of both the computers.

$1890 +1 728 = 3618$

Therefore, total sp = $3618

Since, SP is bigger than CP, therefore, it is obvious that the whole transaction is a profit

Now,

$difference = 3618 - 3600 \\ = 18$

Therefore, there has been a profit of $18

Finally, we need to find the profit percentage

$\frac{18}{3600} \times 100\%$

$= \frac{1800}{3600} \%$

$= \frac{1}{2} \%$

$\frac{1}{2} \% = 0.5\%$

Therefore, the overall profit is 0.5%

Answer 2

Answer:

Photosynthesis is a process where by energy from light is harvested and used to drive synthesis of organic carbohydrates from carbon dioxide and water. Photosynthesis takes place in chloroplasts and can be divided into two steps: light reactions which require light and dark reactions which do not require light.
