Total cost of 10 stickers = 10*12 = Rs. 120 Total cost of 8 stickers = 8*11.75= Rs. 94 => The cost of remaining 2 stickers = 120- 94 = Rs. 26 Let the price of each sticker be x and y. => x + y = 26---------------- (1) And x = 160% of y = 1.6y => 2.6y = 26 y = 26/2.6= 10 and x = 26- 10= 16 So, the price of each of the two stickers is Rs. 10 and Rs. 16 respectively.
