Answer: cost of an alloy is Rs. 312
Explanation:
Given,
Tin and Lead are in the ratio of 3:2
1Kg of tin = Rs.30
1Kg of lead = Rs.20
to find: cost of 12 kg alloy
=Tin: Lead
=3/5*12 : 2/5*12
=7.2: 4.8
Tin (in KG)= 7.2KG
Lead(in KG)=4.8KG
Cost of tin= 30*7.2
=Rs. 216
Cost of lead= 20*4.8
=Rs.96
the total cost of alloy = 216+96
=Rs. 312
