Question

5 bananas and four apples cost as much as three bananas and seven apples.The ratio of the cost of one banana to that of one apple is

Answer 1

Answer:

Step-by-step explanation

let cost of each banana be rs. x

let cost of each apple be rs.y

∴5x + 4y = 3x + 7y

or, 5x - 3x  = 7y - 4y

or, 2x = 3y

or 2x/3y = 0

or x/y = 3/2

∴The ratio is 3 : 2

   

Answer 2

Answer:

3/2

Step-by-step explanation:

let bananas be x:

and apples be y:

then given 5x+4y = 3x+7y

then 5x - 3x = 7y - 4y

=> 2x = 3y

x/y = 3/2

which can also be represented as 3:2
