$\large{\underline{\underline{\mathbf \orange{✟\:Solution:-}}}}$

　　　　　　　　　　　 

Money spent on food = $\sf { \frac{1}{4} \: of \: 8400 }$

　　　　　

　　　　  $\tt:\implies{}$ $\sf {= ( \frac{1}{4} \times 8400) \: = 2100}$

　　　　　　　　　　　 

Money spent on rent = $\sf {\frac{1}{7} \: of \: 8400}$

　　　　　

　　　　  $\tt:\implies{}$$\sf {= ( \frac{1}{7} \times 8400) \: = 2100}$

　　　　　　　　　　　 

Remaining money = $\sf {8400-2100-1200}$

　　　　　

　　　　　$\tt:\implies{}$$\sf {=5100}$

　　　　　　　　　　　 

Money spent on the children = $\sf { \frac{1}{3} \: of \: 5100}$

　　　　　

　　　　　$\tt:\implies{}$ $\sf { = ( \frac{1}{3} \times 5100 ) = 1700}$

　　　　　　　　　　　 

Total money spent = $\sf {2100+1200+1700}$

　　　　　

　　　　　$\tt:\implies{}$$\sf {= ₹5000}$

　　　　　

Money left with him = $\sf {8400- 5000}$

Answer 2

$\bf{\underline{\underline \blue{Solution:-}}}$

$\sf\underline{\red{\:\:\: Given:-\:\:\:}}$

Jasbir's monthly salary is 9600. He spends $\sf {\dfrac{1}{4} }$

of his salary on food and out of the remaining, he spends

on rent and $\sf {\dfrac{1}{6} }$

on education of his children.

$\sf\underline{\red{\:\:\: Need\:To\: Find:-\:\:\:}}$

• How much does he spend on each part?
• How much money is left with him?

$\bf{\underline{\underline \blue{Explanation:-}}}$

$\begin{gathered}\dashrightarrow \sf {Money \:spent \:on\: food = \dfrac{1}{4}\: of \:Rs. \:9600} \\ \end{gathered}$

$\begin{gathered}\dashrightarrow \sf {Money\: spent \:on \:food = Rs. \bigg(\dfrac{1}{4} \times 9600\bigg) } \\ \end{gathered}$

$\begin{gathered}\dashrightarrow \sf {Money\: spent \:on \:food = Rs.\: 2400} \\\\ \end{gathered}$

$\begin{gathered}\dashrightarrow \sf {Remaining \:money \:with \:him = Rs. \:9600 - Rs. \:2400} \\ \end{gathered}$

$\begin{gathered}\dashrightarrow \sf {Remaining \:money \:with \:him = Rs. \:7200} \\\\ \end{gathered}$

$\begin{gathered}\dashrightarrow \sf {Money \:spent \:on\: rent = \dfrac{1}{5} \:of \:Rs. 7200} \\ \end{gathered}$

$\begin{gathered}\dashrightarrow \sf {Money\: spent \:on \:rent = Rs. \bigg(\frac{1}{5} \times 7200\bigg) } \\ \end{gathered}$

$\begin{gathered}\dashrightarrow \sf {Money \:spent \:on\: rent = Rs. \:1440} \\\\ \end{gathered}$

______

$\begin{gathered}\dashrightarrow \sf {Money\: spent \:on \:education \:of \:children = \dfrac{1}{6}\: of \:Rs.\: 7200} \\ \end{gathered}$

$\begin{gathered}\dashrightarrow \sf {Money\: spent \:on \:education \:of \:children = Rs. \bigg(\dfrac{1}{6} \times 7200\bigg) } \\ \end{gathered}$

$\begin{gathered}\dashrightarrow \sf {Money\: spent \:on \:education \:of \:children = Rs. \:1200} \\\\ \end{gathered}$

_____________________________

$\begin{gathered}\dashrightarrow \sf {Total \:money \:spent = Rs. 2400 + Rs. 1440 + Rs. 1200} \\ \end{gathered}$

$\begin{gathered}\dashrightarrow \sf {Total\: money \:spent = Rs. \:5040} \\\\ \end{gathered}$

$\sf\underline{\green{\:\:\: ThereFore:-\:\:\:}}$

$\begin{gathered}\dashrightarrow \sf {Money\:left\:with\: him = Rs. 9600 - Rs. 5040} \\ \end{gathered}$
