Following pls find my worked solution:

R : G

120 : 100

6 : 5

O = 50 + 6p

Given that 298 red and orange beads were used for all the bracelets and 20% of each of the colored beads was used,

(1/5)R + (1/5)O = 298 beads

(6/5)p + 10 + (6/5)p = 298

(12/5)p = 298 - 10 = 288 beads

1p = 288 × (5/12) = 120 beads

(1/5)G = 1p = 120 beads

Given that 20% of each of the colored beads was used to make a total of 22 bracelets,

(1/5)R + (1/5)G + (1/5)O = 22 bracelets

298 + 120 beads = 22 bracelets

418 beads = 22 bracelets

1 bracelet = 418 ÷ 22 = **19** beads

==========

Trust this helps.

Do let me know again if there's further clarification.

Cheers,

Edward
