Explanation:

Rs 6, Rs 8 and Rs 9 per 100 grams means Rs Rs 60, Rs 80 and Rs 90 per kg
84 is middle number between 80 and 90
So take ratios as:
60…………………..90
……………84
6…………………..24
Ratio is 6 : 24 = 1: 4
AND
80…………………..90
……………84
6…………………..4
Ratio is 6 : 4 = 3: 2
So final ratio is 1 : 3 : (4+2) = 1: 3: 6
