a kg of coffee, find the cost of each per kg. by comparison method​

Answer 1

Answer:

tea cost 5.2 rs per kg

coffee cost 5 rs per kg

Step-by-step explanation:

let the cost of tea per kg be x

let the cost of coffee per kg be y

4x + 6y = 50.8

x - 0.2 = y

x -y = 0.2

4x + 6y = 50.8

6x - 6y = 1.2

10x = 52

x = 52/10

=  5.2

x = 5.2

y = 5.0
