x×80/100=1536

x=153600/80

x=1920

CP=Rs1920

Answer 2

Answer:

Cost price of the bicycle is 1920 rupees.

Step-by-step explanation:

Given,Gurudeep lost 20% by selling a bicycle for 1536 rupees.

Therefore, selling price $= 1536 \: rupees$

and loss$= 20\%$

We know,x% loss $= (100 - x)\%$

So,20% loss

$= (100 - 20)\% \\ = 80\%$

Here we want to find cost price of the bicycle.

We know,cost price $= 100\%$

Here 80% means 1536 rupees.

and 1% means $\frac{1536}{80} \: rupees$

and 100% means

$\frac{1536}{80} \times 100 \\ = 1920 \: rupees$

Therefore cost price of the bicycle is 1920 rupees.

This is a problem of Profit and Loss,
