Question

If SP of 15 candle is equal to CP of 16 candle find the gain or loss percent

Answer 1

SP of 15 candle=CP of 16candles
SP=16
CP=15
Gain=SP-CP
=16-15
=1
Gain%=Gain/CP*100
1/15*100
=20/3%
=6.67%

Answer 2

Answer

It is given that cost of 12 candles is equal to the selling price of 15 candles.

It means the ratio of CP and SP is 5:4.

Let the CP of candle be 5x ans SP of candle be 4x.

Therefore the loss percentage is 20%.
