Answers
cost price 540
sale price 614 approx
Step-by-step explanation:
Given :
profit % = 12%
profit = 540
_______________________________
Finding cost price -
Let cost price = x
profit percentage on cost price = 12x/100
According to the given question
x + \dfrac{12x}{100} = 540x+
100
12x
=540
\dfrac{100x + 12x}{100} = 540
100
100x+12x
=540
100x + 12x = 540 \times 100100x+12x=540×100
112x = 54000112x=54000
x = \dfrac{54000}{112} =482.14x=
112
54000
=482.14
x = 482.14 \: (approxmately \: 482 \: )x=482.14(approxmately482)
Cost price is Rs 482.
________________________________
Checking the profit -
CP + (CPxprofit %)
= 482 + (482 x 12/100)
= 482 + 57.84 (Approx 58 )
= 482 + 58
= 540. ( which is already given )
________________________________
Finding the Selling Price -
SP = CP + Profit
SP = 482 + 540
SP = 1022.

Hence :
\bold{Cost \: price \: is \: Rs \: 482}CostpriceisRs482
\bold{Selling \: price \: is \: Rs \: 1022}Selling price is Rs 1022
