Overall loss % = (a2/100) % = (202/100) % = 4%
Thus, seller gets 4% loss in the deal.
Let the cost price = Rs. N, loss = 20% and SP = Rs. 64
N = (100/80) x 64 = Rs. 80
Now, CP = Rs. 80, and gain = 20%
so SP = (120/100) x 80 = Rs. 96
Let CP of first article = Rs. x
CP of second article = Rs. (600 - x)
SP of first article = Rs. (122x / 100)
SP of second article = Rs. [92(600 - x)/100]
? {122x/100} + {92(600 - x)/100} = 600
? 122x - 92x = 60000 - 92 x 600
? 30x = 4800
? x = 160
? CP of the article sold at a loss = (600 - x) = Rs 440
Let CP Rs. x
Then, (110x / 100) - (75x / 100) = 21
? 35x = 2100
? x = Rs. 60
Let the CP of each motorcycle be Rs.N then
(2 x 1.15 x N) + 4800 = 2 x 1.2 x N
? 0.1 x N = 4800
? N = 48000
Let the CP of one articles be Rs. 1
Then, the SP be Rs. 1.25
Again the new SP be (1.25) x 1.2 = 1.5
Now, if he sell initially 100 articles, then
CP = 100 x 1 = Rs. 100
SP = 100 x 1.25 = Rs. 125
New SP = 75 x 1.5 = 112.5 (since 25% articles were abducted)
Therefore, new profit percentage = 12.5%
SP of first book = Rs. 24, gain = 20%
CP of first book = (100/120) x 24 = Rs. 20
SP of second book = Rs. 24, loss = 20%
CP of second book = (100/80) x 24 = Rs. 30
Total CP = (20 + 30) = 50
Total SP = (24 x 2) = Rs. 48
Loss = (50 - 48) = Rs. 2
So, on the whole, there is a loss of Rs. 2
Let the cost price of watch A = Rs. N
Then, cost price of watch B = Rs. (650 - N)
Now, selling price of watch A = (120 x N) / 100 = Rs. 6N/5
Also, selling price of watch B = (650 - N) x (75/100) = Rs. {3 x (650 - N)}/4
As, according to the question, two selling prices are equal.
? 6N/5 = {3 x (650 - N)}/4
? 8N = 5 x (650 - N)
? 8N + 5N = 5 x 650
? 13N = 5 x 650
? N = (5 x 650)/13 = 250
? Cost price of watch A = Rs. 250
and cost price of watch B = (650 - 250) = Rs. 400
SP = Rs. 63000, Profit = 5%
? CP =Rs. (100/105) x 63000 = Rs. 600000
If SP would have been Rs. 500000, then there would have been a loss of 162/3% .
Suppose CP = Rs. 100
? Gain on Rs. 25 = Rs. 2.50
? SP = Rs. 27.50
Loss on Rs. 75 = Rs. 15
? SP = Rs. 60
? Total SP = 60 + 27.50 = Rs. 87.50
? Loss = Rs. 12.50 i.e. 12.5% loss.
Let the cost price of 20 mangoes = Rs. N
CP of 1 mango = Rs. N/20
SP of 1 mango = Rs. N/16
Gain = SP - CP = N/16 - N/20 = Rs. N/80
Gain percentage = {(N/80) / (N/20)} x 100 % = 25%
