The ratio of copper and zinc in brass is 11 ∶ 14. How much amount (in kg) of copper will be there in 150 kg of brass?

The ratio of copper and zinc in brass is 11 ∶ 14. How much amount (in kg) of copper will be there in 150 kg of brass? Correct Answer 66

GIVEN: 

The ratio of copper and zinc in brass = 11 ∶ 14

FORMULAE USED:

Amount of Copper : Amount of Zinc = 11 : 14

CALCULATION:

According to question

11x + 14x = 150

25x = 150

x = 6

∴ Amount of Copper = 11x = 66 kg
