$\sf\green{\underline{✯ Given :- }}$

• The cost of 4/5 estate (plot of land with a large house) is ₹42,000.

$\sf\green{\underline{✯ To \: find :- }}$

• The worth of whole estate, and
• Also the the value of 3/7 of it.

$\sf\green{\underline{✯ Solution :- }}$

• Lets assume that the worth of whole state is :- ₹x.

Now,

$\sf \implies \: \sf\frac{4}{5} \: of \: an \: estate \: worths = ₹\frac{4x}{5}$

According to the question :-

$\sf \implies \: \frac{4x}{5} = 42000 \\ \sf \implies 4x = 5 \times 42000 \\ \bf \implies \: x = \frac{5 \times \cancel{ 42000}}{ \cancel4} \\ \bf \implies \: x = ₹10500$

$\sf\therefore \: worth \: of \: \frac{3}{7} \: of \:i t \: : - \\ \sf = \frac{3}{7} \times x \\ \sf \: = \frac{3}{ \cancel7} \times \cancel{10500} \\ \sf = 3 \times 1500 \\{\pink \bigstar{\underline {\boxed{ \tt = ₹4500 \:\:☞\:\: ans.}}}}$
