Find the gain or loss percent when :
P (1) CP = 620 and SP = 713
(ii) CP = * 675 and SP = 630
Find the selling price when :
(i) CP = ? 1650 and gain % = 4%
(ii) CP = 875 and loss % = 12%
Find the cost price when :
SP = 1596 and gain % = 12%
= %
SP = 34.40 and gain% = 7
The cost price of 12 candles is equal to the selling​

Answer 1

Answer:

Given CP =RS 620.

SP=RS 713

gain =SP-CP= 713-620

gain = RS 93.

∴ gain % =  

cp

gain

​  

×100=  

620

93

​  

×100

gain % =  

62

930

​  

 = 15.

gain % = 15%

Let  SP of one candle be Rs.1

Then SP of 15 candles= Rs. 15

Hence, CP of 12 candles=Rs.15

And SP of 12 candles=Rs.12

Therefore loss = CP−SP = Rs.15−Rs.12= Rs.3
