To find:

• Value of the quantity

Assumption:

• Let the unknown quantity be x.

Solution:

According to the question,

$\displaystyle \implies 35\% \:of\: x = Rs280 \\ \\ \implies \dfrac{35}{100}*x = 280 \\ \\ \implies \dfrac{35x}{100} = 280 \\ \\ \implies \dfrac{7x}{20} = 280\\ \\ \implies x = \dfrac{280*20}{7} \\ \\ \implies x = 40 * 20 \\ \\ \implies \textbf{x = 800 } \\ \\ \text{The unknown quantity is Rs800. } \\ \\ \\ HOPE\:IT\:HELPS!!!!!$
