Q:

A car owner buys petrol at Rs 7.50, Rs. 8 and Rs. 8.50 per litre for three successive years. What approximately is the average cost per litre of petrol if he spends Rs. 4000 each year ?

A) 6.23	B) 7.98
C) 8.97	D) 9.89

Answer & Explanation Answer: B) 7.98

Explanation:

Total quantity of petrol consumed in 3 years =(4000/7.50+4000/8+4000/8.50) liters

= 4000(2/15+1/8+2/17) liters

= 76700/51 liters

Total amount spent = Rs. (3 x 4000) = Rs. 12000.

$\therefore$ Average cost = Rs. (12000*51/76700) = Rs. 7.98.
