cost of mangoes = 90 / kg

cost of grapes = 230 / kg

let the kgs of mangoes she bought be x and kgs of grapes be y

she bought 3 kgs less than four times the amount of grapes for mangoes ie;

kgs of mangoes she bought, x = 4y - 3

cost of mangoes she bought = 90 ( 4y - 3 )

The total cost of the mangoes she bought = 450

90 ( 4y - 3 ) =450

360y - 270 = 450

360y =450+270

360y = 720

y = 2

x = 4y - 3

x = 4*2 -3

x = 8 - 3

x = 5
