Answer 1

Answer:

raghu bought total 1400 beads

Step-by-step explanation:

given colour : blue , red, green, black

let the total beads be x

therefore blue beads = 28% of x =0.28x

red bead = (5/7) × 0.28x = 0.20x

given red bead × 2 = green bead

therefore green bead = 0.20x × 2 = 0.40x

therefore black bead = x - ( 0.28x + 0.20x + 0.40x)

= 0.12x

given blue bead - black bead = 224

therefore 0.28x - 0.12x = 224

0.16x = 224

x = (224÷16)×100

x = 1400
