Let the CP of 15 kg apples = Rs x
SP of 15 kg apples = Rs 2100
Profit % = 12.5%
⇒[ProfitCP×100]% = 12.5 %
⇒[profitx×100] = 12.5
⇒100 profit = 12.5x
⇒100[SP − CP] = 12.5 x
⇒100[2100−x] = 12.5x
⇒210000 − 100x = 12.5x
⇒112.5x = 210000
⇒x = 210000112.5 = Rs 21000001125 = Rs(56003)
CP of 15 kg apples = Rs(56003)     Profit % = 15%
⇒[ProfitCP×100]% = 15 %
⇒profit5600×3×100 = 15
⇒profit = 280
⇒SP − CP = 280SP − 56003 = 280
⇒SP = 280 + 56003
⇒SP = 840+56003
⇒SP = Rs(64403)SP of 15 kg apples = Rs(64403)SP of 1 kg apple = 64403÷15 = 64403 × 115 = Rs 143.10
