Answer 2

Answer:

Given:-

By selling an article for ₹900, a person lost 10%. Find the C.P. of the article.

To Find:-

C.P. of the article.

Note:-

●》C.P. usually means cost price, at which amount the article is purchased and S.P. means selling price, at which amount the article is Sold ( Here, At ₹900 the article is sold so it is S.P. ).

●》To find C.P. ( as loss percentage is given ) = S.P. × 100 / 100 - Loss percentage

●》For checking, if we multiply the loss percentage with C.P. and the sum subtracted to C.P. , it must be = S.P.

Solution:-

S.P. ( Selling price ) = ₹900, Loss percentage = 10

☆ According to note second point ( C.P. = S.P. × 100 / 100 - loss percentage )~

▪︎$C.P. = S.P. × 100 / 100 - loss \ \ percentage$

▪︎$C.P. = ₹ 900 × 100 / 100 - 10$

☆ After doing both numerator and denominator calculations~

▪︎$C.P. = ₹90000 / 90$

☆ After doing calculations ( dividing )~

▪︎$C.P. = ₹1000$

Checking:-

♤ Acoording to note third point ( for checking)~

• $C.P. × loss \ \ percentage$

• ₹1000 × 10%

♤ As percentage is there, so the number denominator will be 100.

• $₹1000 × 10/100$

• $₹100$

♤ So the calculations is ₹100 and now let's subtract with C.P. and check is it same as price of S.P. ? So~

• $C.P. - calculations \ \ of \ \ loss \ \ percentage \ \ with \ \ C.P. = S.P. ?$

$₹1000 - ₹100 = ₹900 ?$

• $₹900 = ₹900 ?$

Yes!

Hence, proved that C.P. = ₹1000

Answer:-

The C.P. of the article is = ₹1000.
