Answer:
9000
Step-by-step explanation:
Monthly earning = 28000
To find the money spent on food, multiply the part of money spent (2/7) on food with the monthly earning.
[tex]\sf \text{Money spent on food = $\dfrac{2}{7}*28000$ }[/tex]
= 2 * 4000
= 8000
Subtract 8000 from the monthly earning and this will give the remaining amount after the money spent on food.
Remaining amount = 28000 - 8000
= 20000
To find the money spent on rent, multiply the part of money spent (1/10) on rent with the remaining amount.
[tex]\sf \text{Money spent on rent = $\dfrac{1}{10}*20000$}[/tex]
= 2000
Subtract 2000 from the 20000 and this will give the remaining amount after the money spent on rent.
Remaining amount = 20000 - 2000
= 18000
To find the other expenses, multiply the part of money spent (1/2) on other expenses with 18000.
[tex]\sf \text{Other expenses = $\dfrac{1}{2}* 18000$}[/tex]
= 9000
Money left with him = 18000 - 9000
= 9000
