Answer:
55% Aluminium oxide is present in 100 tonnes of Bauxite
Explanation:
100 tonnes bauxite produced 50 tonnes of Aluminium oxide
Out of the remaining 50 tonnes that goes as red mud, 10% has Aluminium oxide
= (10÷100)x 50 = 5 tonnes
Total amount of Aliminium oxide is 50 + 5 = 55 tonnes
Perentage of Aluminium oxide in the Bauxite =(55÷100)×100
=55%
