A company’s four cars running 12 hrs a day consume 1200 lts of fuel in 10 days. In the next 6 days, the company will need to run 9 cars for 12 hrs each so it rents 5 more cars which consume 20% less fuel than the company’s four cars. How many lts of fuel will be consumed in the next 6 days?	Choose the correct option:
A) 1200 lt	B) 1440 lt	C) 1664 lt	D) 1728 lt	E) 4800 lt
Given that   4 cars running 12 hrs a day consume 1200 lts. of fuel in 10 days.   1 car consumption per hour per day = 1200 /4 *12 *10 = 2.5 litre   Now question say new car consume 20% less fuel than the company’s four cars = 80/100 of 2.5 = 2 ( 20 percent less than 2.5)   Hence we calculate total consumption for next 6 days, the company will need to run 5 new cars for 12 hrs = 2 *12 *6*5= 
<gadget id="calculator">2 *12 *6*5</gadget>
<output>720</output>
720   similarly= old 4 car consumption for next 6 days for 12 hrs =2.5*6*12*4= 
<gadget id="calculator">2.5*6*12*4</gadget>
<output>720</output>
720   hence total is= 720+720= 
<gadget id="calculator">720+720</gadget>
<output>1_440</output>
1440 lt   Ans is 1440 lt .
<result>B</result>
