CP of whole lemons = Rs 600∴ CP of 34th of the lemons = Rs34 × 600 = Rs 450and CP of 14th of the lemons = Rs 14 × 600 = Rs 150Now loss on selling 34th of the lemons = 20%∴ SP of 34th of the lemons = CP 100 - loss%100                                                    = 450 100 - 20100                                                    = 450 × 80100 = Rs 360Profit on selling 14th of the lemons = 20%∴ SP of 14 of the lemons = CP 100 + profit%100= 150 100 + 20100= 150 × 120100 = Rs 180∴ total SP of whole lemons = Rs 360 + Rs 180 = Rs 540∴ loss = CP - SP    as, CP > SP              = 600 - 540 = Rs 60∴ Loss% = loss ×100CP = 60 × 100600 = 10%
