Answer 2

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
