A company’s four cars running 10 hrs a day consume 1500 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 answer:
A) 1200 lt
B) 1555 lt
C) 1664 lt
D) 1728 lt
E) 2160 lt
Given that   4 cars running 10 hrs a day consume 1200 lts. of fuel in 10 days.   1 car consumption per hour per day = 1500 /4 *10 *10 = 3.75 litre   Now question say new car consume 20% less fuel than the company’s four cars = 80/100 of 3.75 = 3 ( 20 percent less than 3.75)   Hence we calculate total consumption for next 6 days, the company will need to run 5 new cars for 12 hrs = 3 *12 *6*5= 
<gadget id="calculator">3 *12 *6*5</gadget>
<output>1_080</output>
1080   similarly= old 4 car consumption for next 6 days for 12 hrs = 3.75*6*12*4= 
<gadget id="calculator">3.75*6*12*4</gadget>
<output>1_080</output>
1080   hence total is= 1080+1080= 
<gadget id="calculator">1080+1080</gadget>
<output>2_160</output>
2160 lt   Ans is 2160 lt .
<result>E</result>
