A taxi driver filled his car petrol tank with 40 litres of petrol on Monday. The next day, he filled the tank with 50 litres of petrol. If the petrol costs Rs 44 per litre, the driver spends Rs 3960 for all petrol filled.

Determining the expenditure in all the filled fuel:

• Petrol filled on Monday by a taxi driver in his car = 40 litres
• Petrol filled on Tuesday by a taxi driver in his car = 50 litres
• Total petrol filled in the car by taxi driver = 40 + 50 = 90 litres
• Since the cost of 1 litre of petrol = Rs 44

Cost of 90 litres of petrol = 44 x 90 = Rs 3960

### The formula for Multiplication

Calculating the sum of two or more numbers is the process of multiplication. It is stated as "a multiplied by b" when two numbers, let's say "a" and "b," are multiplied. Multiplication in mathematics is essentially just adding a number repeatedly in relation to another number.

The formula for multiplication is provided by:

Multiplier × Multiplicand = Product

The total number of objects in each group is known as the multiplicand. The multiplier is how many groups are equivalent. The outcome of multiplying the multiplicand by the multiplier is the product.

Hence, the driver spends Rs 3960 on all petrol filled.

Summary:

## A taxi driver filled his car petrol tank with 40 litres of petrol on Monday. The next day, he filled the tank with 50 litres of petrol. If the petrol costs Rs 44 per litre how much did he spend in all on petrol?

On Monday, a taxi driver filled the tank of his vehicle with 40 litres of gasoline. He added 50 litres of gasoline to the tank the following day. If a litre of gasoline costs Rs 44, the driver will have to pay Rs 3960 for all of his fill-ups.
