The cost price of 12 candles is equal to the selling price of 15 candles. Find the loss percent.

Let the CP of 12 candles = SP of 15 candles = Rs x.

Then, CP of 1 candle = Rs (x/12)

SP of 1 candle = Rs (x/15)

Loss = CP - SP = Rs { (x/12) - (x/15) } = Rs { (5x - 4x)/60 } = Rs x/60.

Now, loss percent = (Loss/CP)*100%.

  = { (x/60) / (x/12) } * 100%

  = { (x/60) * (12/x) } * 100%

  = 20%

Therefore, there is a loss of 20%.

Hope it helps.

Cheers!!!

CP of 12 candles = SP of 15 candles
let the CP of 1 candle be rs.1
CP of 12 candles = rs.12
CP of 15 candles = rs.15 
SP of 15 candles = rs.12 

Loss = rs 15 - rs 12 = rs.3

Loss% = loss/CP * 100 
            = 3/15 * 100 =300 / 15 =  20%

Answer :- The loss percent is 20 ( 20%)

Let the cost of 1 candle be x.
Therefore, total CP = 12x
SP = 15x
As, SP is greater than the CP, there is a loss.
Loss = SP-CP


=15x - 12x
=3x

Loss % = Loss / CP*100
= 3x / 15x * 100 ( As CP=SP)
=1 / 5 * 100
= 20 %

I hope that helped Aradhya!

Let the CP of each candle = Rs.1
CP of 12 candles = SP of 15 candles
                            = Rs.15

Let the SP of each candle = Rs.1
SP of 15 candles = CP of 12 candles
                           = Rs.12

Loss = CP - SP
        = 15 - 12 = Rs.3

Loss percent = (Gain/CP * 100)%
                     = (3/15 * 100)%

                    = 20%

Hope it helps.
