Question

The ratio of tin and iron mixed in and alloy is 3:5 . Find the weights of tin and iron in 872g of the alloy.​

Answer 1

Answer:

• Tin : Iron = 3 : 5
• Alloy containing tin and iron = 872 gm

Let the weight of Tin and Iron be 3x and 5x respectively.

• According to the Question :

⇒ Alloy = 872 gm

⇒ Tin + Iron = 872 gm

⇒ 3x + 5x = 872 gm

⇒ 8x = 872 gm

⇒ x = 872 gm / 8

⇒ x = 109 gm

⠀⠀⠀⠀⠀───────────────

• Weights of Tin and Iron :

⇢ Tin = 3x = 3(109 gm) = 327 gm

⇢ Iron = 5x = 5(109 gm) = 545 gm

Answer 2

Tin : Iron = 3 : 5

Alloy containing tin and iron = 872 gm

Let the weight of Tin and Iron be 3x and 5x respectively.

• According to the Question :

⇒ Alloy = 872 gm

⇒ Tin + Iron = 872 gm

⇒ 3x + 5x = 872 gm

⇒ 8x = 872 gm

⇒ x = 872 gm / 8

⇒ x = 109 gm
