2. for this ques, suppose tat 100% wastage is thr.. using A, 25% is saved. now 75% is wastage.. using B, 20% is saved.. ie. 75*20/100=15... ie. 15part of tat 75 is saved.. so the wastage now will be 75-15=60.. using C,10% is saved..ie. 60*10/100=6.. 60-6=54.. finally by combinin A,B & C the wastage is 54.. the saved fuel(fuel economy) is 100-54=46 |
