CP = (100/120) x 2220 = ? 1850
CP = [100/(100 + Gain%)] x SP
= (8960 x 100)/128
= 70 x 100 = ? 7000
Let SP = SP = ? 100
? CP = ? 95
Profit = 100 - 95 = ? 5
Profit % = (Profit/CP) x 100%
= (5/95) x 100% = 5.26%
Given, CP = ? 350 and gain = 15%
? SP = [(100 + Gain%) / 100] x CP
= (115/100) x 350 = 115 x (7/2)
= ? 402.50
CP of the article = (180 x 100)/90 = ? 200
To gain 10% SP of article = 110% of 200 = ? 220
Let cost price be ? N.
Selling price = 2345
Loss = 19%
Cost price, N = (SP x 100)/(100 - Loss%)
= (2345 x 100)/(100 - 19%)
? N = 234500/81 = ? 2895 ? ? 3000
CP = [100/(100 - Loss%) ] x SP
CP = 6000 x (100/75) = 8000
Since, CP of 2 lemon is ? 1
? CP of 1 lemon is = 1/2 = ? 0.5
SP of 5 lemon is ? 3.
? SP of 1 lemon is = 3/5 = ? 0.6
? Gain percent = [(0.6 - 0.5)/0.5] x 100
= (0.1/0.5) x 100 = 20%
Let CP = ? 100
? SP = [75 x (124/100)] + 25
= 93 + 25 = ? 118
Clearly, gain % = 18%
Here, a = 22 and b = 20, then
? Gain% = [(a - b)/b] x 100%
= [(22 - 20)/20] x 100% =10%
Here, a = 23, b = 20
? Required percentage profit = [(a - b)/b] x 100 %
= [(23 - 20)/20] x 100% = 15%
