A company’s four cars running 10 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 15% less fuel than the company’s four cars. How many lts of fuel will be consumed in the next 6 days? Select:
A) 1200 lt
B) 1555 lt
C) 1664 lt
D) 1782 lt
E) 4800 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 = 1200 /4 *10 *10 = 3 litre   Now question say new car consume 15% less fuel than the company’s four cars = 85/100 of 3 = 2.55 ( 20 percent less than 3)   Hence we calculate total consumption for next 6 days, the company will need to run 5 new cars for 12 hrs = 2.55 *12 *6*5= 
<gadget id="calculator">2.55 *12 *6*5</gadget>
<output>918</output>
918   similarly= old 4 car consumption for next 6 days for 12 hrs = 3*6*12*4= 
<gadget id="calculator">3*6*12*4</gadget>
<output>864</output>
864   hence total is= 918 +864= 
<gadget id="calculator">918 +864</gadget>
<output>1_782</output>
1782 lt   Ans is 1782 lt .
<result>D</result>
