Question

5 mangoes and 4 oranges cost as much as 3 mangoes and 7 oranges then the ratio of the cost of one mango to that of one orange is

Answer 1

let one mango be x
and one orange be y
so 5x+4y=p
and 3x+7y=p
from first equations we have
5x+4y=3x+7y
on simplyfying
2x=3y
x/y=3/2
so the ratio of cost of one mango to one orange is 3:2
Done :D

Answer 2

Answer:

The ratio of cost of one mango to that of one orange is 3:2.

Step-by-step explanation:

First let us write the given in terms of a equation,

Cost of 5 mangoes and 4 oranges = Cost of 3 mangoes and 7 oranges

Cost of 5 mangoes – Cost of 3 mangoes = Cost of 7 oranges – Cost of 4 oranges  

On subtracting we get,

Cost of 2 mangoes = Cost of 3 oranges.

(Cost of 1 mango)/(Cost of 1 orange)=3/2

Cost of 1 mango : Cost of 1 orange = 3:2.
