Question

The average consumption of petrol for a car for seven is 110 litres and for
next five months it is 86 litres. Then find the average monthly consumptions​

Answer 1

Answer:

average monthly consumption is 100liters

step by step explanation:

Average consumption = total consumtion / number of months

given average consumption for 7 months is 110 liters

110=total 7 months consumption /7

Total 7 month consumption =110×7=770liters..similarly given,

Average consumption for 5 months is 86 liters

Total 5month consumption =86×5=430 liters

To get average monthly consumtion,

Average consumption=(770+430)/(7+5)

average monthly consumption is 1200/12=100liters
