I'm going to assume that the question should say “at a profit of 5%”.
Restate question in the form of a equation.
Let C = the cost price of the item.
C + 0.705 C = C - 0.05 C + Rs 50
0.05 C = - 0.05 C + Rs 50
0.10 C = Rs 50
C = Rs 500
The cost price of the item is Rs 500
I hope this help you

Hello :
calculate : x , y , z :
1) logx = 0.8821
2) logy = 7.8821
3) logz = 1.8821
note : loga = b equiv : a= 10^b ... a <span>> 0
so :
x = 10^(0.8821) = 7.62 y = 10^(7.8821) = 76225450.54
z = 10^(1.8821) = 76.22</span>

Answer:
Solution is (1,7).
Step-by-step explanation:
We need to find the solution of the system of following equations.
y= 5x + 2 eq(1)
3x = -y +10 eq(2)
We will solve the equations using Substitution method to find the values of x and y
we put value of y from eq (1) into eq (2), The eq(2) will be:
3x = - (5x + 2) + 10
3x = -5x -2 +10
3x+5x = -2+10
8x = 8
x= 1
Now, putting value of z in eq(1) to find value of y
y = 5x +2
y = 5(1) + 2
y = 5+2
y = 7
So, Solution is (1,7).
