He sells 95 litre petrol at the price of 100 litre.
So profit % = [ 5 / 95 ] X 100 = 5.26%
Abhishek Discount = 2800
Bhanu Discount =2400+640=3040
The difference in selling price is same as difference in discount = 3040 - 2800 = Rs.240
K = 1 litre, price of K = 1
P = 4 litre price of P = 2
price of total (new) mixture = 1 X 1 + 4 X 2 = Rs. 9
price of pure petrol of same quantity = 5 X 2 = Rs. 10
Percentage profit = [(10-9) / 9] x 100 = 111/9 %
? 1 dozen = 12
? 1/4 dozen = 1/4 x 12 = 3
? Cost of 3 bananas = Rs. 2.35
? Cost of 1 banana = Rs. 2.35/3
? Cost of 42 x 12 bananas = (2.35 x 42 x 12 ) / 3
= Rs. 394.80
= Rs. 400 (Approximately)
? Total cost of 7000 bricks = 5740 + 805 = Rs. 6545
? Total cost of 1 brick = Rs. 6545/7000
? Total cost of 1000 bricks = (6545 / 7000) x 1000
= Rs. 935
S.P. = Rs. 100, gain = Rs. 10
? C.P. = S.P. - gain = Rs. 90
? Gain% = (10 / 90) x 100 % = 111/9%
Let C.P. of each table = Re. 1
C.P. of 20 tables = Rs. 20
S.P. of 20 table = C.P. of 15 tables = Rs. 15
? loss = (5/20) x 100 % = 25%
S.P. = Rs. 1980, Gain = 10%
? C.P. = Rs. (100 / 110) x 1980 = Rs. 1800
Suppose he buys 8 toffees
Then, C.P. = Re. 1
Gain = 60%
? S.P. = Rs. (160 / 100 x 1) = Rs. 8 / 5
For Rs. 8 / 5, toffees sold = 8
For Re. 1 toffees sold = (8 x 5) / 8 = 5
So, he must sell them at 5 for a rupee
C.P. of 330 boxes = Rs. (7200 + 200 + 600) = Rs.8000
S.P. of 330 boxes = Rs. (330 x 28) = Rs. 9240
? Gain % = (1240 / 8000) x 100 % = 15.5%
