25 kg of alloy X is mixed with 125 kg of alloy Y. If the amount of lea...
Ratio of lead and tin in the alloy X = 1 ∶ 2;
∴ Amount of lead in 25 kg of alloy X = (1/3) × 25 = 25/3 kg
And amount of tin in 25 kg of alloy X = (2/3) × 25 = 50/3 kg
Ratio of lead and tin in the alloy Y = 2 ∶ 3;
∴ Amount of lead in 125 kg of alloy Y = (2/5) × 125 = 50 kg
And amount of tin in 125 kg of alloy Y = (3/5) × 125 = 75 kg
∴ Total amount of lead after mixing alloy X and Y = 25/3 + 50 = 175/3 kg
And total amount of tin after mixing alloy X and Y = 50/3 + 75 = 275/3 kg
∴Ratio of lead and tin in the mixture = (175/3) / (275/3) = 7 ∶ 11
