Answer 1

I'll do one, then you can show har far you get on the others. Just put the words into symbols and solve the resultant equation(s).

#1.
If the two TVs cost x and y, then

1.15x = 3450
x + y = 1.15x + .90y
So, x = 3450/1.15 = 3000
.1y = 3450-3000 = 450
y = 4500

The two TVs cost 3000 and 4500
check:
90% of 4500 = 4050
cost: 3000+4500 = 7500
income: 3450+4050 = 7500

Answer 2

Thanks bro

Answer 3

Let the cost of 1st TV be x
And sceond TV be y
So,
Let CP be 100
And as the gain is 15 so SP is 115
Given SP is 3450
Profit of 1st TV is15%
Loss of sceond TV is 10 %
According to the question-
115% of x is 3450
1.15x=3450
100-10%=90%
=0.90
So,
X+y= 1.15x + 0.90 y
X=3450/1.15=3000
0.1y=3450-3000=450
So,
Y = 450/0.1=4500
Therefore the cost of sceond TV is 4500
