Question

A trader marks up his goods by 120% and offers 30% discount. What will be the selling price (in Rs) if the cost price is Rs 750?

A) 1225 B) 1080 C) 1280 D) 1155

Answer 1

Sᴏʟᴜᴛɪᴏɴ :-

→ Cost price = CP = Rs.750

→ Excess marking over cost price = 120%

So,

→ Marked Price = 750 + {(750*120)/100} = 750 + 900 = Rs.1650

Now,

→ marked price = 1650

→ Discount = 30%

→ SP = {MP * (100 - D%)}/100

→ SP = {1650 * (100 - 30)} /100

→ SP = (1650 * 70) / 100

→ SP = 165 * 7

→ SP = Rs.1155 (D) (Ans.)

Hence, Selling price is Rs.1155.

❃ A trader marks up his good by 120% and offers 30% discount . What will be the selling price (in Rs.) if the cost price is Rs. 750?



${ \huge{ \pink{ \underline{ \underline{ \mathfrak{Solution:-}}}}}}$




${ \bold{ \green{GIVEN- }}}$



➧ Cost price (C.P. ) = Rs. 750


➧ excess marking on the good = 120%


➧ Discount = 30%


${ \bold{ \green{ TO \: FIND- }}}$



➧ Selling Price (S.P. ) ???



${ \red{ \star{ \underline{ \underline{ \: \: Marked \: Price \: (M.P.)}}}}}$



${ \bold{M.P. = 750 + ( \frac{120}{100} \times 750)}}$



${ \bold{ \implies{M.P. = 750 + (12 \times 75)}}}$



${ \bold{ \implies{M.P. = 750 + 900}}}$



${ \bold{ \implies{ \red{M.P. = Rs. \: 1650}}}}$



➧ Discount = 20%



${ \red{ \star{ \underline{ \underline{ \: \: \: Selling \: Price \: (S.P.)}}}}}$



${ \underline{ \boxed{ \bold{ \pink{S.P. = \frac{M.P. \times (100 - discount \: prcnt)}{100}}}}}}$



${ \bold{S.P. = \frac{1650 \times (100 - 30)}{100}}}$



${ \bold{ \implies{S.P. = \frac{1650 \times 70}{100}}}}$



${ \bold{ \implies{S.P. = 165 \times 7}}}$



${ \boxed{ \boxed{ \bold{ \implies{ \red{S.P. = Rs. \: 1155}}}}}}$



therefore,


➧ Selling Price (S.P. ) = Rs. 1155


thus, option (D) is correct...
