151.537 liters

Out of monthly 15000 km. driven 30% or 15000*30/100=4500 Km. driven by van, So 70% or 15000*70/100=10500 Km. driven by truck.
Consumption of fuel(in liters) by old trucks & Vans=(10500/18) +(4500/13)=217500/234
Consumption of fuel(in liters) by new trucks & vans=(10500/23)+(4500/14)=250500/322
So saving by using new trucks & vans=(217500/234)-(250500/322)=929.487 - 777.95=151.537

Ans 151.537
very simple,just understand the question by reading it.. it seems lengthy but the logic is easy..
Trucks- 10500 Vans – 4500
10500/18 = 583 litres 4500/13 = 346 litres
10500/23 = 456 litres 4500/14 = 321 litres
583+ 346= 929 litres 456+ 321=777 litres

Difference 929-777= 152(approx) or 151.537
