Answer 1

Answer:

The Saving of Mike is Rs 10000

Step-by-step explanation:

Let the saving of mike be x

Income of Jimmy = Rs 20000

Expenditure of Jimmy = Rs 14000

Thus Jimmy's Saving = Rs 20000-Rs 14000= Rs 6000

Ratio of Jimmy and mike saving is 3:5.

Using the ratio and proportion property

\begin{gathered}3:5=6000:x\\\\\Rightarrow \frac{3}{5}=\frac{6000}{x}\\ \\\end{gathered}

3:5=6000:x

⇒

6000

Isolate x by dividing 6000 on both sides.

\begin{gathered}\Rightarrow \frac{3}{5\times 6000}=\frac{6000}{x\times 6000} \\\\\Rightarrow \frac{1}{10000}=\frac{1}{x}\end{gathered}

⇒

5×6000

=

x×6000
