Question

the ratio of silver to tin in an alloy is 2:3 find percentage of tin in the alloy

Answer 1

let the amount be 2x and 3x
2x+3x=5x
percentage of silver=2x/5x×100
=40%
percentage of silver=3x/5x×100
=60%

Answer 2

Let the amount of silver and tin be 2a and 3a


Total = 5a

Percentage of tin = Amount of tin *100 / Total

= 3a*100 / 5a

= 300a/5a

= 300/5

= 60


Required % = 60%
