- Check only ratio for quick solve. 15:25:60=3:5:12 . here 5kg for 25% led so 12kg for60%copper and 3kg for 15% cobalt. Nothing change in rstio so direct ans 12kg. Quick ans in one min

- 25%=5kg
100%=20kg
60% of 20 kg= 12kg
12 kg..... - 9 years agoHelpfull: Yes(26) No(0)
- 5 Kg of led = 25% of the mixture
so Total Mixture(100%) is 20 Kg
Now copper used for 20 kg mixture is : 20 * (60/100) = 12 Kg - 9 years agoHelpfull: Yes(6) No(0)
- if we consider total mixture = X kg
led = 5kg
(25/100)*X = 5
X = 20kg
so the amount of copper is =>
(60/100)*20 = 12Kg - 9 years agoHelpfull: Yes(6) No(0)
- 25%=5kg
60%=?
?=(60*5)/25=12kg - 9 years agoHelpfull: Yes(2) No(0)
- in mixture total total led is used=5/25*100=20kg...... and
60% of 20 kg is copper
so 20*60/100=12kg copper is used.............. - 9 years agoHelpfull: Yes(1) No(0)
- cost od 5% is 1 then 60% cost will be= 60/5=12 kg copper
