Question

The value of a machine depreciated by
10% per year during the first two years and
15% per year during the third year. Express
the total depreciation of the machine, as
percent, during the three years. USING X NOT USING 100​

Answer 1

Answer:

The answer of this question is 31.15%

Answer 2

\begin{gathered} \sf{ = \frac{10}{3}} \\ \end{gathered} \sf\frak\orange{ = 3.33\%}=3.33%\begin{gathered} \sf{ = \frac{10}{3{ \cancel{00}}}\times1{\cancel{00}}} \\ \end{gathere ni To find the concentration of sol. first we have to find the the volume of solution.So let's calculate,

V of sol. = 10 + 290

V of sol. = 300ml

Therefore, Concentration of sol.

\begin{gathered} \sf{ = \frac{10}{3{ \cancel{00}}}\times1{\cancel{00}}} \\ \end{gathered}

=

\begin{gathered} \sf{ = \frac{10}{3}} \\ \end{gathered}

=

\sf\frak\orange{ = 3.33\%}=3.33%

Hence, the required

concentration of solution is 3.33%d}
