Loss % = ( common gain or loss / 10 )2 %
= (20 / 10)2 %
= 4%
CP / SP = 29x / 19x
loss % = 29x - 19x / 29x X 100 = 34.48 %
(To understand the concept assume CP of each article Rs 29 and SP of each article = Rs. 19)
Go through option C
180 x 12 x 1.2 + 180 x 8 x 1.1 = 180 [ 14.4 + 8.8 ]
= 180 (23.2) = 4176
And 180 x 20 x 1.15 = 4140
Therefore loss = 4176 - 4140 = 36
Hence option (c) is correct
CP of A + B + c = 2xy + 5x*2y - 2x*4y = 20xy
profit of A = 0.2xy
profit of B = 2xy
profit of C = 2xy
Total profit = 4.2xy
% profit = (4.2xy / 20xy) X 100 = 21%
Let the price be y , then
y x 0.8 x 0.9 = 468
? x=650, therefore marked price = Rs. 650
Alternatively : 650 X 0.8 X 0.2 = 468
Hence option (d) is correct
Let the original price be 100 Rs.
So reduced price = 100 X 0.95 X 0.90 X 0.80 = 68.40
? Single discount = (100 ? 68.4) % = 31.6%
Loss % = ( common gain or loss / 10 )2 %
= (20 / 10)2 %
= 4%
Now assume total CP of both articles be x, then SP = 0.96x = 400
x = 400 / 0.96 = CP
loss = 4% of CP
= (4 / 100) X (400 / 0.96) = Rs. 16.66
Its simple i.e. 25% nothing else, which is very obvious
He sells 95 litre petrol at the price of 100 litre.
So profit % = [ 5 / 95 ] X 100 = 5.26%
6.66% of MP = 25
? MP = 375
? SP = MP - 25 = 350
Abhishek Discount = 2800
Bhanu Discount =2400+640=3040
The difference in selling price is same as difference in discount = 3040 - 2800 = Rs.240
