Question

what will be the cost per kg of the mixture of two types of teas mixed in the ratio 3:2,if the first type is purchased in rs.200 per kg and the second type in rs.300 per kg​

Answer 1

Answer:

240 rupees

Step-by-step explanation:

let X is the cost of the mixture

then,

3:2 = (300-X) / (X-200)

3/2 = (300-X) / (X-200)

3*(X-200) = 2* (300-X)

3X - 600 = 600 - 2X

5X = 1200

X = 240

hence , cost of the mixture is 240 rupees
