hope this helps a little bit! sorry i couldn’t help with all of them
Answer:
rs 200
Step-by-step explanation:
Let cost price = x
At 30% profit; marked price of radio is 30% of x = (100% + 30%) = 130%x
Discount = rs 3%
Profit made = 30
Hence,
Marked price - discount = cost price + 30
130%x - 30 = x + 30
1.3x - 30 = x + 30
1.3x - x = 30 + 30
0.3x = 60
Divide both sides by 0.3
0.3x / 0.3 = 60/ 0.3
x =
1.3x / 1.3 = 60 / 1.3
x = 200
Hence, cost price = rs 200
The last one
because you are reflecting it over the x-axis

![\left[\begin{array}{ccc}-1&2&1\\1&-4&1\\-2&-2&1\end{array}\right]](https://tex.z-dn.net/?f=%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-1%262%261%5C%5C1%26-4%261%5C%5C-2%26-2%261%5Cend%7Barray%7D%5Cright%5D%20%20)
Find the determinant
D = [(-1).(-4).1 + 2.1.(-2) + 1.1.(-2)] - [1.(-4).(-2) + (-1).1.(-2) + 2.1.1]
D = [4 - 4 - 2] - [8 + 2 + 2]
D = -10 - 12
D = -22
A = |D|/2
A = |-22|/2
A = 22/2
A = 11
