Question

​

Answer 1

Answer:

here is your answer

Step-by-step explanation:

For example

Two types of tea A and B are mixed and then sold at Rs. 40 per kg. The profit is 10% if A and B are mixed in the ratio 3 : 2, and 5% if this ratio is 2 : 3. The cost prices per kg of A and B are in the ratio

21 : 25

Let Tea A and B be sold at Rs.a and Rs.b respectively

When A and B are mixed in the ratio 3 : 2 and sold at a profit of 10% at Rs.40 per Kg

3a+2b5 = 401.1 ------(1)

When A and B are mixed in the ratio 2 : 3 and sold at a profit of 5% at Rs.40 per Kg

2a+3b5 = 401.05 ------(2)

Solving equations (1) and (2), we get

1.1 × (3a+2b5) = 1.05 × (2a+3b5)

1110 × (3a + 2b) = 2120 × (2a + 3b)

66a + 44b = 42a + 63b

24a = 19b

ab = 1924

So, the cost prices per Kg of A and B are in the ratio 19 : 24
