Question

The ratio of weights of copper and tin in bronze is 22:3. Find the weight of tin in a bronze article weighing 500g.

Answer 1

Given, the weights of copper and tin are in the ratio 22 : 3

Let the constant be x

Let the weight of coper be 22x and weight of tin be 3x

Guven, the weight of tin in a bronze article weighing is 500g


According to the question,

22x + 3x = 500

➾ 25x = 500

➾ x = $\dfrac{500}{25}$

➾ x = 20



Weight of copper ➾ 22x

➾ 22 × 20

➾ 440 grams



Weight of tin ➾ 3x

➾ 3 × 20

➾ 60 grams

Answer 2

let the weight of copper be 22x and tin be 3x
therefore
22x+3x=500
25x=500
x=500/25
x=20gm
22x=22×20
=440 gms
3x=3×20=60gms
