Answer 1

Given :

• The selling price (S.P.) of α shirt is Rs.800.
• Loss percent is 20%

To Find :

• Cost price of the shirt.

Knowledge Required :

$\large\star{\boxed{\sf{\pink{ C.P. \:when\:loss\%\:is\:given = \dfrac{ SP\times 100}{ 100-loss\:percent}}}}}$

Solution :

• Substitute the vαlues in the formulαe of C.P αnd simplify.

$\longrightarrow{\sf{ C.P. = \dfrac{100\times 800}{ 100- 20}}}$

$\longrightarrow{\sf{ \dfrac{80000}{80}}}$

$\longrightarrow{\sf{ \dfrac{\cancel{80000}}{\cancel{80}}}}$

$\large\longrightarrow{\boxed{\sf{\purple{ Rs.1000}}}}$

Hence, the cost price of the shirt is Rs. 1000.

And we αre done! :)
