Of the new vehicles registered in a week, 300 were neither SUVs nor were they powered by diesel. 3/4th of the SUVs registered were diesel powered and there were half as many SUVs as there were non SUVs. If SUVs not powered by diesel were a sixth of non SUVs not powered by diesel, how many vehicles V registered in the week were powered by diesel?  Answers: A) 50 B) 150 C) 200 D) 250 E) 400
Supposing that 'x' is the number of vehicles of SUV.   0.25*x = non diesel SUV   0.75*x = diesel SUV   0.5*x = only diesel   By supposition,   0.25*x = 1/6*300   =&gt;x = 200   Therefore, number of vehicles powered by diesel is V =150+100=
