Question

a 20% of a 6 litre solution and 60% of a 4 litre mixed. what percentage of the mixture of solution

Answer 1

Ans is 36%

 

solid in first solution= 20/100*6=1.2 kg

Solid in second solution=60/100*4=2.4Kg 

total solid in final solution=1.2+2.4=3.6

final volume=10 lit

final mixer %=3.6*100/10=36%

Answer 2

20% of 6 lt=6/5 lt

60% of 4 lt=12/5 lt

 

total=18/5

 

hence final %=(18/5)/(10)*100

=36%
