Answer: Option C
Solution(By Examveda Team)
While buying,He buys 1100 gram instead of 1000 gram.
Suppose he bought 1100 grams for Rs. 1000.
While selling, He sells only 900 grams when he takes the money for 1 kg. Now, according to the problem, he sells at a 8% profit (20% markup, 10% discount). Hence, his selling price is Rs. 1080 for 900 grams. Now, 1100 grams for Rs. 1000 Hence, 1188 grams for Rs. 1080 Selling: 900 grams for Rs. 1080 Hence, % profit = $$\frac{{288}}{{900}}$$ × 100 = 32% (using goods left by goods sold formula).

Let CP = 100
MP = 120
SP = 120 - 10% of 120 = 108.
now, he buys 1100 gram instead of 1000 gram.
so, CP of 1gm = 100/1100 = 1/11
He sells only 900 grams at the money for 1 kg
so, SP of 1gm = 108/900 = 3/25
so, gain = 3/25 - 1/11 = 8/275
Therefore, gain % = (gain/cp) *100 = [(8/275)/(1/11)] *100 = (8/25)*100 = 800/25 = 32
so gain is 32%
Let C.P=100
S.P=100*120/100*90/100*110/100*100/90=132
✓p%=S.P-C.P=132-100=32
Hence 32%P
100×(6/5)×(9/10)×(11/10)×(10/9) = 132
∴ Profit% = (132 - 100) = 32%
Applying multiplying factor concept :
100*(6/5)*(9/10)*(11/10)*(10/9)= 132
So, profit = (132-100) = 32%
120×90×1000×1100/100×100×900×1000=32%
Price increased by 20% it mean 120 and he gives discount 10% so it become 90 then he cheat by 100gm while buying and selling ,in buying it become 1100 and in selling it become 900 so it gives 32%
How 1080 came
How 1188 came
@Bhavya
Let CP = 100
MP = 100 + 20% of 100 = 120
SP = 120 - 10% of 120 = 108.
Profit % = (8 *100)/100 = 8%.
This is a simple assumption.
Formula for calculating profit% when discount and m.p given ..
P%= m%-d%-md/100
So
P%= 20-10-200/100
= 8%
