Olympiad Test: Subtraction - 2 - Class 4 MCQ

• Subtraction: Subtraction is used when we have to find how many more to be subtracted to get the given number.


• Example: If we have a number 10 and we need to find out how many more need to be subtracted to get 6, we will use subtraction. The answer will be 4.


• Opposite of Addition: Subtraction is the opposite operation of addition. When we subtract, we are finding the difference between two numbers.


• Comparison: Subtraction is used to compare two numbers and find out how much one number is greater or smaller than the other.


• Mathematical Operations: Subtraction is one of the basic mathematical operations along with addition, multiplication, and division.

• Total pages in the book: 119


• Pages read: 59

• Pages left to be read: Total pages - Pages read


• Pages left to be read: 119 - 59 = 60

• Therefore, Shraddha has 60 pages left to read in her book.

• Start by subtracting the last two digits of the numbers: 84 from 00. This gives us 16.


• Next, subtract the hundreds digits: 8 - 5 = 3.


• Combine the results to get the final answer: 3000 + 16 = 6416.

Therefore, 8000 - 1584 = 6416.

• Step 1: Subtract 1524 from 20000 to find the missing number


• 20000 - 1524 = 18476

Therefore, the missing number is 18476, which is option A.

• Step 1: Start by subtracting the ones place: 0 - 9 = -9


• Step 2: Since 0 cannot be subtracted from 9, borrow 1 from the tens place, making it 8 in the tens place and adding 10 to the ones place (10 - 9 = 1).


• Step 3: Now subtract the tens place: 8 - 9 = -1


• Step 4: Finally, subtract the hundreds place: 9 - 1 = 8

Now, putting the results together, we get:

• Thousand's place: 9 - 1 = 8


• Hundred's place: 0 - 9 (borrowing 1 from thousand's place) = -9


• Tens place: 8 - 9 (borrowing 1 from hundred's place) = -1


• Ones place: 10 - 9 (borrowing 1 from tens place) = 1

Therefore, the result of 9000 - 1999 is 7001, which matches option B.

• Start by subtracting the ones place: 9 - 4 = 5


• Next, subtract the tens place: 4 - 3 = 1


• Finally, subtract the hundreds place: 5 - 2 = 3

• So, 3549 - 1234 = 2315

• Option A: 2315

Therefore, the correct answer is 2315.

• Start by subtracting the ones place: 3 - 9 = -6


• Borrow 1 from the tens place: 4 becomes 3 and add 10 to the ones place: -6 + 10 = 4


• Subtract the tens place: 3 - 9 = -6


• Borrow 1 from the hundreds place: 6 becomes 5 and add 10 to the tens place: -6 + 10 = 4


• Subtract the hundreds place: 5 - 9 = -4


• Borrow 1 from the thousands place: 5 becomes 4 and add 10 to the hundreds place: -4 + 10 = 6


• Subtract the thousands place: 4 - 2 = 2

• 5643 - 2999 = 2644

Remaining eggs = 1647 – 234 = 1413

• Talwar family consumes 1000 kgs of wheat in a year


• Mehra family consumes 959 kgs of wheat in a year


• To find out how much more kgs of wheat does Talwar family consume, we subtract the wheat consumption of Mehra family from Talwar family

• 1000 kgs - 959 kgs = 41 kgs

• Therefore, Talwar family consumes 41 kgs more wheat than Mehra family in a year.

• Number of cars = 2198


• Number of bikes = 1212


• Difference = Number of cars - Number of bikes


• Difference = 2198 - 1212 = 986

• There were 2198 cars and 1212 bikes in the parking area.


• To find out how many more cars were there than bikes, we subtract the number of bikes from the number of cars.


• Therefore, there were 986 more cars than bikes in the parking area.
