Let CP = 3x and SP = 7x
According to the question,
7x = 700
? x = 100
? CP = 3x = ? = 300
Here, a = 23, b = 20
? Required percentage profit = [(a - b)/b] x 100 %
= [(23 - 20)/20] x 100% = 15%
Here, a = 22 and b = 20, then
? Gain% = [(a - b)/b] x 100%
= [(22 - 20)/20] x 100% =10%
Let CP = ? 100
? SP = [75 x (124/100)] + 25
= 93 + 25 = ? 118
Clearly, gain % = 18%
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%
CP = [100/(100 - Loss%) ] x SP
CP = 6000 x (100/75) = 8000
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 = x
According to the question,
625 - x = x - 435
? 2x = 1060
? x = 1060/2 = ? 530
Let CP = N
According to the question
(106N/100) - (104N/100) = 3
? 2N/100 = 3
? N = 300/2
= ? 150
Profit on one calculator
= 250[1- (100/114)] = ? 30.70
? Total amount of the profit
= 19 x 7 x 30.70
= ? 4083.10
Here, 6 apples are gained over 18 apple.
? Gain percent = (6/18) x 100 %
= 331/3%
