A truck traveling at 70 miles/hr consumes 30% more fuel than another that is traveling at 50 miles/hr.If truck traveling at 50 miles/hr has fuel efficiency of 19.5 miles/litre.Then how many miles can the truck traveling at 70 miles/hr travel on 10 litre of fuel
136
140
150
130
120

• truck A is taking 30% more fuel THAN truck B...
  if B consumes 1 litre (for 19.5 miles), then A consumes 1.3 litre (for the same distance i.e 19.5 miles)...
  
  A consumes 1.3lt for -->>19.5 miles
  so,it will consume 10lt for-->> 19.5*10/1.3
  
  i.e 150 miles

• At 50 mph, fuel consumed per litre = 1/19.5 ltrs
  At 70 mph, fuel consumed per litre = 1.3/19.5= 1/15 ltrs
  means 1 litre of fuel is reqd for 15 miles
  hence with 10 ltrs of fuel, truck can travel 150 miles.

• 19.5miles/llitre...in 10 litre it will cover 195 miles...so distance covered by first truck in 10 liter,,,,195-30%of 195=136.5~136 miles i think so
