Question

if the cost price of 13 chocolates is equal to the selling price of 14 chocolates . find the profit or loss percent?

Answer 1

s.p of chocolates = 14x
c.p of chocolates = 13x
so,
profit = s.p - c.p
= 14x - 13x
=X
profit % = profit / c.p × 100
X / 13x × 100
100x / 13x = 7.69

Answer 2

Explanation:

Cp Of 1 chocolates = Rs.1

Then Cp Of 12 chocolates = 12

And Sp Of 12 chocolates = 15

Gain = Sp-Cp= 15-12 = 3

Gain% = (Gain/Cp)*100 %

= (3/12)*100

= 25%

12 S P = 15 C P

S P = 5/4 C P

= 125% C P

Profit % = 25 %

12*(SP) = 15*(CP)

12*(CP+P) = 15*(CP)

12P = 3*CP

P = CP/4

Gain% = P*100/CP

= CP*100 / (CP*4)

= 25%
