Copper makes up 64% of the alloy mass, and the rest is zinc. How many grams of zinc is contained in 750 tons of alloy?

1) Find out how much zinc is in the alloy, if it is known that 64% is copper.

100 – 64 = 36%.

20 Let’s find out what is the mass of zinc in 750 tons of alloy.

750 – 100%

X – 36%;

X = 750 * 36/100;

X = 270 t.

Answer: the mass of zinc in 750 tons of alloy is 270 tons.
