Question

Sagar purchased 10 kg of rice at the rate of 15 per kg and 25 kg of rice at the rate 14 per kg. He mixed the two and sold the mixture. Approximately at what rate per kg should he sell the mixture to mal
40% profit in the transaction?​

Answer 1

20per kg

Step-by-step explanation:

Total money spent on buying rice is (10x15)+(25x14) = 500

if X is the total amount for which he is going to sell then[ (X-500)/500]x100 = 40

Thus X=700 and 700/35 = 20 is the price per kg

Answer 2

At Rs.20 per kg he should sell the mixture to get 40% profit in the transaction.

Step-by-step explanation:

Since we have given that

Quantity of rice = 10 kg

Cost = Rs. 15 per kg

Quantity of rice = 25 kg

Cost= Rs. 14 per kg

So,it becomes

$10\times 15+25\times 14\\\\=150+350\\\\=500$

So, sell the mixture at 40% profit in the transaction,

$\dfrac{100+40}{100}\times 500\\\\=140\times 5\\\\=700$

Cost per kg would be

$\dfrac{700}{35}=Rs.\ 20$

Hence, at Rs.20 per kg he should sell the mixture to get 40% profit in the transaction.
