Answer 2

$\huge\boxed{\texttt{\fcolorbox{Red}{aqua}{Hey Mate!!!}}}$

$<b><I><font face=Copper black size=4 color=blue>$ Here is your answer.
1) SP = Rs 1260
Discount = 37%

As we know the formula

MP = SP× 100/(100-Discount%)

$= \frac{1260 \times 100}{100 - 37} \\ = \frac{126000}{63} \\ = 2000$
Therefore MP = Rs 2000

4) Discount = 10%. Profit = 20%

Let CP = 100
So SP = 100+20 = 120

Discount =
$= \frac{10}{100} \times 120 \\ = 12$
SP =120- 12
= 108

So Profit = 108- 100
= 8

Profit% =
$= \frac{8}{100} \times 100 \\ = 8\%$
5)
SP = 17940

DISCOUNT = 8% INCLUDE

$mp = \frac{17940 \times 100}{100 - 8} \\ mp = \frac{1794000}{92} \\ mp = 19500$
Now Profit = 19.6%

MP = 19500


$cp = \frac{17940 \times 100}{100 + 19.6} \\ cp = \frac{1794000}{119.6} \\ cp = 15000$
Total Profit = 19500- 15000
=4500

Profit%
$= \frac{4500}{15000} \times 100 \\ = 30\%$
