Let cost price of an article = (220 x 100)/110 = ? 200
For getting the profit of 30%, Selling price of an article = 130% of ? 200
= (130/100) x 200 = ? 260
Let the cost price of article = ? N
Then, 120% of N = 300
? (120 x N)/100 = 300
? N = (300 x 100)/120 = ? 250
Now, SP = ? 235
Then, loss percentage = [(250 - 235)/250 ] x 100 = 6%
Cost price of one bracelet = ? 160
Profit earned = 15%
? Selling price of one bracelet
= Cost Price + Profit earned
= 160 + (160 x 15)/100
= 160 + (16 x 15)/10 = 160 + 240/10
= 160 + 24 = 184 = ? 184
Hence, Meera should sale her bracelet ? 184 per piece.
Let the cost price of the article be ? N.
Now, N + 20N/100 = 3600
? 120N/100 = 3600
? N = 3000
Now, profit percentage when the article is sold for ? 3150 = [(3150 - 3000)/3000] x 100
= (150/3000) x 100 = 5%
SP = ? 120 and loss = 15%
? CP = (100/85) x 120 = 2400/17,
Gain = 2%
? Required SP = (102/100) x (2400/17) = ? 144
Total CP = (CP + Overhead expenses)
= 150 + 12% of 150
= 150 + (12/100) x 150 = ? 168
Given that, gain = 10%
? SP = (110/100) x 168 = ? 184.80
Let the cost price of the shoes = ? x
According to the question,
2033 - x = x - 1063
? 2x = 2033 + 1063 = 3096
? x = 3096/2 = ? 1548
Let CP = ? 100, then SP = 140
New CP = ? 60 and new SP = (60 x 150)/100 ? 90
According to the question,
?(140 - 90) = ? 50 is equivalent to ? 5.
? ? 100 is equivalent to ? 10.
? CP = ? 10
Let CP of the watch be ? N.
Then , According to the question,
[(75 - N)/ N] x 100 = N
? (75 - N) x 100 = N2
? N2 + 100N - 7500 = 0
? N2 + 150N - 50N - 7500 = 0
? N(N + 150) - 50 (N + 150) = 0
? (N + 150) (N - 50) = 0
? N = ? 50
Let each lot of onion-contain N kg onion,
Then total cost price of these two lots together = 10N + 15N = 25N
Selling price of whole lot = 15 x (N + N) = 15 x 2N = 30N
Profit percentage = [(30N - 25N)/25N] x 100 %
= (5/25) x 100%
= 20%
SP of 1 lemon = ? 14/5
Let CP of 1 lemon = N
According to the question, (N x 140)/100 = 14/5
? N = ? 2
? CP for 12 lemons = 12 x 2 = 24
