Let C.P. per kg be Rs. x then,
x - 10% of x = 5.40
? x = 6
? Required S.P. = Rs. [6 + 20% of 6] = Rs. 7.20
Price after 1 st discount = 80% of Rs. 160 = Rs. 128
Price after 2nd discount = 90% of Rs. 128 = Rs. 115.20
Let the cost price of article be P.
So from question,
Selling price = P + P%
? 144 = P + (P x P)/100
? 144 x 100 = 100P + P2
? P2 + 100P - 14400 = 0
? (P - 80)(P +180) = 0
? P = 80
Let C.P. = Rs. 100
? Marked price = Rs. 120,
? S.P. = Rs. 108
? Rate of discount = (12/120) x 100% = 10%
Let the cost price be Rs. 100.
So market price = 100 + 10% of 100 = 110
Selling price = 110 - 10% of 110 = 99.
So, net loss = 1%
Rate of discount = (12 / 80) x 100% = 15%
Given that, CP = ? 200 and SP = ? 225
Profit = SP - CP = 225 - 200 = ? 25
? Gain% = [profit/CP] x 100%
= (25/200) x 100% = 12.5%
Given that CP = ? 500 and SP = ? 300
Loss = CP - SP = 500 - 300 = ? 200
? Loss % = (Loss/CP) x 100%
= (200/500) x 100% = 40 %
Given, total sale= ? 791000
? Cost price = (791000 x 100) /113 = ? 700000
? Required profit = 791000 - 700000 = ? 91000
CP of bracelet = [100/(100 - Loss%)] x SP
= (100/80) x 14500
= ? 18125
SP = 125% of CP [? SP = {(100 + Gain%)/100} x CP]
= {125/100} x 40
= (5/4) x 40 = 5 x 10 = ? 50
