The three-coffee blend is in 8+11+21=40 parts. Ratio of indonesian to brazilian is 11 : 21.

For a mix containing 63 kg of indonesian, find brazilian, b using proportion
11%2F21=b%2F63

%2811%2A63%29%2F21=33------kg of the brazilian coffee



1424 kg of the three coffee blend

African, 1424%288%2F40%29=285
Indonesian, 1424%2811%2F40%29=392
Brazilian, 1424%2821%2F40%29=748
