Gain% = {Error / (True value - Error)} x 100 %
= (100/900) x 100) %
= 111/9%
Let original of each toy be Rs. 100 and number originally sold be 100.
? originaly sale proceeds = Rs. (100 x 100) = Rs. 10000
New sale proceeds = Rs. (120 x 85) = Rs. 10200
? Increase% = (200 x 100 / 10000)% = 2%
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%
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
Let S.P. = Rs. 100
Then C.P. = Rs. 40
? Required percent = (100/40) x 100% = 250%
Let original price = Rs. 100
Price after 1 st discount = Rs. 90
Price after 2 nd discount = Rs. (80/100) x 90 = Rs. 72
Price after 3 rd discount = Rs. (60/100) x 72 = Rs. 43.20
? Single equivalent discount = (100 - 43.20) = 56.8%
Loss% = (Common gain or loss% / 10)2
= (10 / 10)2 = 1%
Loss% ( common gain or loss % / 10)2
= ( 5/10 )2 = 1/4 % = 0.25%
Let C.P. = Rs. x then, 425 - x = x - 355
? 2x = 780
? x = 390
2 x + y = 7000 ....(i)
x + 2 y = 9800 .....(ii)
Solving (i) and (ii), we get,
y = 4200
10% profit - 10% loss = 6
? 20% of cost price = Rs. 6
? Cost Price = (6 x 100)/ 20 = Rs. 30.
