3 guavas and 2 apples cost 155 pesos, while 5 guavas and 4 apples cost 285 pesos. What is the cost of each guava?

Answer 1

Step-by-step explanation:

let's take cost of guavas =x and cost of apples =y

according to problem,

3x+2y=155....(1)

and 5x+4y=285....(2)

by elimination method,

equation (1)×2=6x+4y=310

equation (2)×1=5x+4y=285

x=25

therefore, cost of each guava =25
