Given:
Selling price of a machine = 7000/-
Gross loss = 20%.
To find:
The cost and gross loss.
Solution:
Let x be the cost of machine.
According to the question,




Divide both sides by 0.8.


So, the cost of the machine is 8750/-.
Now,



Therefore, the gross loss is 1750/-.
Answer:

Step-by-step explanation:




First, let's introduce a variable:
Let n represent the number we are trying to find.
20 % x n = 58
0.20 x n = 58
0.20n = 58
n = 290
Therefore, 58 is 20% of 290.

ZX is √b²+a²
Step-by-step explanation:
From the diagram you notice that length WX is a and length WZ is b.ZX is the diagonal length formed by triangle ZWX.Apply the Pythagorean relationship here the sum of squares of the two sides equals the square of the diagonal.Hence;
ZW²+ WX²=ZX²
b²+a²=ZX²
√b²+a²=ZX
