Answer
CP is the cost price.
Gain% = CP%
Gain or profit = CP * CP/100
SP = CP + profit = CP + CP²/100 = 24
CP² + 100 CP - 2400 = 0
CP = [ -100 +- √(10,000 + 9, 600) ] /2
= 20 taking only the positive value.
So Rs 20 is the cost price and 20% is the gain.
=========================
CP² + 100 CP - 2, 400 = 0
(CP - 20) ( CP ( + 1200) = 0 So CP = 20
