Question

Find the CP if SP is rupees 10240 and loss is 20 percentage.

Answer 1

In context to question asked,

We have to determine the value of CP.

As per question,

It is given that,

SP = Rs. 10240

Loss percentage = 20%

As we know that,

Profit and loss are calculated on CP.

So, Loss will be 20% of CP.

Hence, value of Loss will be

$=\frac{20}{100}\times CP\\=>0.2CP$

As we have the formula for finding SP in term of CP.

We know that,

$SP = CP- Loss\\=>SP = CP -0.2CP\\=>0.8CP = 10240\\=>CP = \frac{10240}{0.8} = Rs.\:12800$

Hence, value of CP will be Rs. 12800.
