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 = (100/30) x 400 = ? 4000/3
[? CP = {100/(100 - Loss%)} x SP]
We know that
Loss = CP - SP
240 = 3200 - SP
? SP = 3200 - 240 = ? 2960
SP = 125% of CP [? SP = {(100 + Gain%)/100} x CP]
= {125/100} x 40
= (5/4) x 40 = 5 x 10 = ? 50
Let SP = SP = ? 100
? CP = ? 95
Profit = 100 - 95 = ? 5
Profit % = (Profit/CP) x 100%
= (5/95) x 100% = 5.26%
CP = [100/(100 + Gain%)] x SP
= (8960 x 100)/128
= 70 x 100 = ? 7000
CP = (100/120) x 2220 = ? 1850
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%
