1.	5) Stickers are bought at 11 for 10 and soldat 10 foräš11, Find the profit per cent.
Answer» 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 %

5) Stickers are bought at 11 for 10 and soldat 10 foräš11, Find the profit per cent.

Answer»

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 %
