    Gold coins = 18000 , Silver coins = 9600 , Bronze coins = 3600 Number which exactly divide all these numbers = HCF of 18000, 9600 & 3600 = 1200 No. of boxes required for gold coins = `18000/1200`   = 15 , No. of boxes required for silver coins = `9600/1200`   = 8 and No. of boxes required for bronze coins = `3600/1200` = 3 Total no. of boxes required = 15 + 8 + 3 = 26
