Question

A alloy consisting of three metals, A, B&C weight 72 kgs in the proportion of 1:2:3. Find the A, B & C weight in the ratio.​

Answer 1

let weight of metal be X

1 metal= X

2nd metal = 2x

3rd metal = 3x ( ratio)

ACC. to question

1x+2X+3x = 72

6x = 72

x = 72/6

x=12 kg

1 metal = 12

2nd metal = 2×12= 24

3rd metal = 3×12 = 36

hence proportion is 12:24:36

Hope it helps
