Answer :
The amount of litres he consume is 26 litres.
He spent a total of €37,70 for 26 litres.
He can buy 40 litres of petrol for € 58
How to find the number of litres the car consume and the cost?
He fills up his car which is 60 litres.
After a certain distance, 340 decilitres remained in the tank.
Therefore, we have to convert the amount of gas remaining in the car to litres.
Hence,
1 decilitres = 0.1 litres
340 decilitres = ?
cross multiply
amount of petrol remaining in the car = 0.1 × 340
amount of petrol remaining in the car = 34 litres
Therefore,
amount of litres consumed = 60 - 34 = 26 litres.
Let's find the cost he spent if 1 litre cost € 1.45.
1 litre = € 1.45
26 litres = ?
amount spent = 26 × 1.45
amount spent = € 37.70
Let's find how many litres of petrol he can buy for € 58.
€ 1.45 = 1 litre
€ 58 = ?
cross multiply
number of litres he can buy with € 58 = 58 / 1.45
Therefore,
number of litres he can buy with € 58 = 40 litres.
