Question

an alloy contains 40% zinc ,25% Copper and the rest is Nickle. Find in grams the quantity of each of the contents in a sample of 1 kg alloy​

Answer 1

Answer:

percentage of nickel = {100-( 40+25)}% = {100-65}% = 35%

1 kg = 1000 gm

then

quantity of zinc = {(40/100)×1000} gm = 400 gm

quantity of copper = {(25/100)×1000} gm = 250 gm

quantity of nickel = {(35/100)×1000} gm = 350 gm
