⟩ If A,B,C are the mechanism used seperately to reduce the wastage of the fuel by 30%, 40%, 10% What will be the fuel economy if they were used Combined?A. 68.4B. 62.2C. 58D. 27
Let each mechanism solution is 100 litre.
In "A" mechanism, wastage is (100-30)/100 = 70 %
In "B" mechanism, wastage is (100-40)/100 = 60 %
In "C" mechanism, wastage is (100-10)/100 = 90 %
If all are combined,total solution = 300 litres
Total wastage = 220 litres
Total used fuel = 80 litres
So, wastage in 100 litres = 80/3 litres
% wastage = 26.6666.... %
= 27 % (approx)
