cost price of 11 stickers = Rs10 cost price of 1 sticker = Rs 10/11 therefore cost price of 10 stickers = Rs 10/11 x 10 selling price of 10 stickers = Rs11 therefore profit = SP -- CP = Rs 11 -- 100/11 = (121 -- 100) /11 = 21/11 therefore profit per cent = P/CP x 100 = 21/11 ÷ 100/11 × 10 = 21 %
Answer:
21 per cent
Step-by-step explanation:
CP=11 stickers for Rs 10.
SP=10 stickers for Rs 11.
LCM Of 10,11=10×11=110
CP of 1 sticker = Rs 10/11
CP of 110 stickers = Rs 10/11×110
= Rs 100
SP of 1 sticker = Rs 11/10
SP of 110 stickers = Rs 11/10×110
= Rs 121
Profit = Rs (SP - CP)
= Rs (121 - 100)
= Rs 21
Profit per cent = (g/CP×100)per cent
=(21/100×100)per cent
= 21 per cent (Ans)
