Answers
Answer:
Ans : Rs.17.7 per kg
Step-by-step explanation:
Solution 1
Total quantity of the mixture = 35 + 45 = 80 kg
Cost price of this 80 kg mixture = 35×12.50 + 45×16.50 = Rs. 1180
Selling price of 80 kg mixture to earn 20% profit =
1180×120100=1416
i.e. ,Selling price of 1 kg mixture to earn 20% profit =
141680=17710=17.7

Let x be the cost price of 1 kg mixture
By the rule of alligation,
12.5 16.5 x 16.5-x x-12.5
16.5-x : x-12.5 = 7 : 9
148.5 - 9x = 7x - 87.5
16x = 236 x = 23616 = 594
Required selling price = 594×120100=17710=17.7 per kg
