Question

A gold ring was sold for rupees
7200 at a loss of 12% find its
cost price​

Answer 1

Step-by-step explanation:

let the CP be ₹100

then the SP would be ₹12 of ₹100 =112

when sp is ₹112 then cp is ₹100 on the loss of ₹12

if sp is ₹7200 then sp= 112/100×7200

CP =₹ 8064

loss = CP -SP

=₹8064-₹7200

=₹864

$\blue{\bold{\underline{\underline{Answer:}}}}$

$\green{\tt{\therefore{Cost\:price=8181.81\:rupees}}}$

$\orange{\bold{\underline{\underline{Step-by-step\:explanation:}}}}$

$\green {\underline \bold{Given:}} \\ \tt: \implies Selling \: Price(S.P) = 7200 \: rupees \\ \\ \tt : \implies Loss\% = 12\% \\ \\ \red{\underline \bold{To \: Find:}} \\ \tt: \implies Cost \: Price = ?$

• According to given question :

$\bold{As \: we \: know \: that} \\ \tt: \implies Loss = 12 \% \: of \: cp \\ \\ \tt: \implies Loss = \frac{12}{100} \times cp \\ \\ \tt: \implies Loss = 0.12 \: cp \\ \\ \bold{As \: we \: know \: that} \\ \tt: \implies Selling \: Price = C.P - Loss \\ \\ \tt: \implies 7200 = C.P - 0.12 \: C.P \\ \\ \tt: \implies 7200 = 0.88 \: C.P \\ \\ \tt: \implies C.P = \frac{7200}{0.88} \\ \\ \tt: \implies C.P = \frac{7200 \times 100}{88} \\ \\ \green{\tt: \implies C.P = 8181.81 \: rupees}$
