A lorry has 28 litres of fuel in its tank. An additional 75 litres is filled. What is the total quantity of fuel in the lorry?

Correct Answer

Given: Fuel in tank = 28 litres Additional fuel filled = 75 litres

Formula: Total fuel = Initial fuel + Additional fuel

Substitution: Total fuel = 28 + 75

Calculation: Ones place: 8 + 5 = 13 (write 3, carry 1) Tens place: 2 + 7 + 1 (carry) = 10 Sum = 103

Explanation

The chapter explains addition using place value. We add 28 and 75 by aligning ones with ones and tens with tens. 8 + 5 = 13 (write 3, carry 1), 2 + 7 + 1 (carry) = 10. So the sum is 103 litres.

Solution Steps

  1. Step 1: Write the numbers with proper place value alignment: 28 + 75

  2. Step 2: Add the ones place: 8 + 5 = 13. Write 3 in ones place, carry 1 to tens place.

  3. Step 3: Add the tens place: 2 + 7 + 1 (carry) = 10. Write 10.

  4. Step 4: The total is 103 litres.
