Question

an alloy consists of 3 metals abc in the proportion of 1:2:3 weight of alloy is 72kg find the weight of abc in the ratio​

Answer 1

Answer:

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

Answer 2

to find the value of x

1x +2x+3x= 72

6x=72

X=72/6

X=12

1x =1*12=12kg

2x=2*12=24kg

3x=3*12=36kg
