Given: Alloy A contains metals gold and bronze in the ratio 5 : 8 Alloy B contains these metals in the ratio 3 : 10 Alloy C is prepared by mixing A and B in the ratio 1 : 1 Calculations: Alloy A ⇒ gold = 5/13, bronze = 8/13Alloy B⇒ gold =
3
13
, bronze =
10
13
⇒ gold =(
5
13
)+(
3
13
)=
8
13
⇒ bronze =(
8
13
)+(
10
13
)=
18
13
⇒ Ratio of gold to bronze =
8
13
:
18
13
⇒ 8 : 18 ⇒ Ratio of bronze to gold = 9 : 4 ∴ Ratio of bronze to gold is 9 : 4.
