Cost Price = 245346 Marked Price(MP) = 1.2× CP = 294415.2 Selling Price of Half item= MP/2 = 147207.6 SP of one-quater item= MP of quater item×.8(20% discount) = (294415.2/4)×.8 = 58883.04 SP of rest = (294415.2/4)×.6 (As only quater item left) = 44162.28 Total SP = 147207.6+58883.04+44162.48= 250252.96 %gain = 250252.96/245346*100= 2%
No need of calculating from given CP. Assume CP to be 100, since MP is 20% above CP thus MP = 120. Now 1/2 stock(i.e 60) @ MP therefore SP(1/2 stock) = 60 Again 1/4 stock (i.e. 30) @ 20% disc thus SP (1/4 stock) = 24. Again rest which is 1/4 stock (i.e. 30) @ 40% disc thus SP(1/4 stock)= 18 Total SP=60+24+18= Rs 102. Since CP was assumed 100. Thus Gain% = 2
