Given, Total quantity of alloy = 2 kg = 2 x 1000 = 2000 grams
% of zinc = 36%
% of copper = 40%
-------------------------------------------------------------------------------------------------------------
% of nickel = (100 - 36 - 40) = 24%
Zinc = 36% of 2000
= 36/100 x 2000
= 720 grams
Copper = 40% of 2000
= 40/100 x 2000
= 800 grams
Nickle = 24% of 2000
= 24/100 x 2000
= 480 grams
Total 720 + 800 + 480 = 2000
Hence , zinc is 720 grams
copper is 800 grams
nickel is 480 grams
