Ribbons : B + Y + G
Blue is 48 cm longer than Yellow
B = Y + 48/100
Green is twice the length of Blue
G = 2B
Total length is 12 m
TOTAL = B + Y + G = 12 M
Y + 48/100 + Y + 2 (Y+48/100) = 12
4Y + 0.48 + 0.96 = 12
4Y = 12 - 0.96 - 0.48
4Y = 10.56
Y = 10.56/4 = 2.64
Length of yellow ribbon = 2.64 m.
B = 3.12 m
G = 6.24 m
2.64+3.12+6.24 = 12 m
