Question

If sp of 15 candlea is equal to cp of 16 candles. Find the gain or loss present?

Answer 1

Let C. P of 16 candles = x.

C. P of one candle = x /16

S. P of 15 candles = x.

S. P of one candle = x/15

Now Gain = x/15 - x/16 = 1/240x

Gain% = x/240 / x/16 * 100 = 16*100/240 = 6.67%

Answer 2

heya !

CP 16 candles = x.

CP 1 candle = x /16

SP 15 candles = x.

SP 1 candle = x/15

Gain = x/15 - x/16
= 1/240x

Gain in percentage = x/240 / x/16 * 100
= 16*100/240
= 6.67%
