Question

23. The cost price of 12 candles is equal to the selling
price of 15 candles. Find the loss per cent? with
x formula​

Answer 1

$\huge \mathbb{ \underline{ \underline\red{ \red{S{ \pink{O{ \blue{L{ \purple{U{ \orange{T { \red{I{ \blue {O{ \green {N{ \: :-}}}}}}}}}}}}}}}}}}}$

$\: \: \:$

$\tt{Let \: SP \: of \: 1 \: candle = Rs. \: 1}$

$\tt{SP \: of \: 15 \: candles = Rs. \: 15}$

$\sf \pink{ \underline{Hence, }}$

$\tt {CP \: of \: 12 \: candles = Rs. \: 15}$

$\tt{SP \: of \: 15 \: candles = Rs. \: 12}$

$\sf \pink{ \underline{Therefore \: Loss}}$

$\tt = CP - SP$

$\tt = 15 - 12$

$\large \boxed { \sf { \red{= Rs. 3}}}$

Answer 2

Answer:

20%

Step-by-step explanation:

CP of 12 candles is = SP of 15 candles = x

CP of 1 candle is = x/12

SP of 1 candle = x/15

Loss = x/12-x/15

= (5x - 4x)/60

= x/60

Loss% = x/60/x/12×100

= x/60×12/x×100

= 20%
