Question

Two alloys A and B contain copper and zinc in the ratio 5:4
and 3:2 respectively. If equal amount of two alloys are mixed
together then find ratio of copper and zinc in the new mixture.​

Answer 1

Answer:

1)Ratio of copper and zinc- 5:4

2) ..... 3:2

Coper 5/9 +3/5, zinc 4/9 +2/5

copper5/9+3/5=25 +27/45=52/45

Zn=4/9 +2/5=20 +18/45 = 38 /,45

Copper: zinc-52/45:38 / 45

= 52:38 = 26:19. Ans
