| The alloy is composed of copper and tin. It contains 60% copper, which is 11/6 kg more than tin. How many kg of copper is in the alloy?
Given:
A – copper mass = 60% of the total alloy
B – mass of tin = 40% of the total alloy
A – B = 11/6
Solution:
1) B / A = 0.4 / 0.6 = 2/3
2) B = 2/3 A – Found the ratio of the mass of the alloys.
3) A – 2/3 A = 11/6
4) 1/3 A = 11/6
5) A = 33/6 = 5.5 (kg) – Substitute the obtained data into the equation.
Answer: 5.5 kg.
