Question

0 An alloy contains zinc and copper in the ratio 5:8 and another alloy contains
zinc and copper in the ratio 5 : 3. If equal amounts of both the alloys are melted
together, then the ratio of zinc and copper in the resulting alloy is:
(a) 25 : 24
(b) 3:8
(c) 103 : 105
(d) 105: 103​

Answer 1

Answer:

d.

Step-by-step explanation:

Zinc in 2 kg of new alloy = (5/13 + 5/8) = 105/104 kg

copper in 2 kg of new alloy = (8/13 + 3/8) = 103/104 kg

Ratio of zinc and copper in new alloy = 105/104 : 103/104 = 105:103
