Here, 6 apples are gained over 18 apple.
? Gain percent = (6/18) x 100 %
= 331/3%
Profit on one calculator
= 250[1- (100/114)] = ? 30.70
? Total amount of the profit
= 19 x 7 x 30.70
= ? 4083.10
Let CP = N
According to the question
(106N/100) - (104N/100) = 3
? 2N/100 = 3
? N = 300/2
= ? 150
Let CP = x
According to the question,
625 - x = x - 435
? 2x = 1060
? x = 1060/2 = ? 530
Let number of apples bought = 5 x 6 = 30 [LCM of 5 and 6]
CP = (10/5) x 30 = ? 60
SP = (15/6) x 30 = ? 75
? Gain = SP - CP = 75 - 60 = ? 15
? Gain % = (15/60) x 100 % = 25%
Let CP = 3x and SP = 7x
According to the question,
7x = 700
? x = 100
? CP = 3x = ? = 300
CP = 405 / 0.9 = 450
New SP = Rs. 465
Profit (%) = [465-450 / 450] X 100 = 3.33%
Price after 10% discount = 10000 - 10 % of 10000 = 10000 - 0.1 x 10000 = 9000
Price after another 20% discount = 9000 - 20 % of 9000 = 7200
Price after 10% of transportation charges = 7200 + 7200 x 0.1 = 7920
Price after 10% of profit = 7920 + 7920 x 0.1 = 8712
? Selling price = 8712
Go through options. Consider option (b)
200 x 3.25 - 200 x 3 = Rs. 50 = ( 30+20 )
Hence option, (b) is correct
Alternatively: Rs. 0.25 is the difference on 1 banana
Rs. 1 is the difference on 1/0.25 = 4 bananas
Rs. 50 is the difference on 4 x 50 = 200 bananas
Profit (%) = goods lefts / goods sold X 100 = ( 50 / 450 ) X 100 = 111/9 %
Alternatively : Suppose CP of 1g is Rs.1 then he sells goods worth Rs.450 only and charges Rs.500. So the profit is Rs.50 over the sale price of Rs. 450.
The best way is to go through option. Consider option (a)
Total profit = 15000 x ( 2 / 3 ) x 5 %
= 15000 x ( 2 / 3 ) x ( 5 / 100) = 500
Total loss = 15000 x ( 1 / 3 ) x 2 %
= 5000 x ( 1 / 3 ) x ( 2 / 100) = 100
Net gain = ( 500 - 100 ) = Rs. 400
Hence: option (a) is correct.
Alternatively : [( 1.05 X 2x/3 + 0.98 x/3) - x] = 400
? x=15000
