Question

A printer is sold for * 7,840 inclusive of 12% GST. Find the marked price of the
printer.​

Answer 1

$\sf{Let \: the \: marked \: price \: of \: the \: printer \: be \: x}$

$x + 12 \: \% \: of \: x \: = \: 7840$

$x + \: \frac{12}{100} \: x \: = \: 7840$

LCM of 1 and 100 is 100

$\sf{\frac{x \: \times 100 + 12}{100} \: = \: 7840}$

$\frac{100x + 12}{100} = 7840$

$100x + 12 = 784000$

$100x = 77988$

$x = 779.88$

$\color{lime} \sf \boxed{ \therefore \: The\:Marked\:price\:of\:the\:heater\:is\:₹\:779.88}$
