Olympiad Test: Multiplication - 2 - Class 4 MCQ

• Multiply 966 by 20


• 966 * 20 = 19320

• When multiplying two numbers, you simply multiply the two numbers together


• In this case, 966 multiplied by 20 equals 19320

• Therefore, the correct answer is A: 19320

• Multiplication: To calculate 987 x 9, we multiply the two numbers as follows:




• 9 x 7 = 63 (write down 3, carry over 6)


• 9 x 8 = 72 + 6 (carry over) = 78 (write down 8, carry over 7)


• 9 x 9 = 81 + 7 (carry over) = 88 (write down 8, carry over 8)




• Final Calculation: Therefore, 987 x 9 = 8883

• 796 x 7 = 5572

• To calculate 796 x 7, we can multiply 796 by 7 in a step-by-step manner.


• Starting from the rightmost digit, 6 x 7 = 42. Write down 2 and carry over 4.


• Moving to the next digit, 9 x 7 = 63. Adding the carried over 4, we get 67. Write down 7 and carry over 6.


• Finally, 7 x 7 = 49. Adding the carried over 6, we get 55. Write down 55.


• Therefore, 796 x 7 = 5572.

Total no. of crayons = 79 × 93 = 7347

• Given: Each of Titu, Jeeti, Janu, and Lalli has 250 Pokemon cards.


• Number of cards each: 250 cards


• Total number of people: 4 (Titu, Jeeti, Janu, Lalli)

• Total cards for Titu: 250 cards


• Total cards for Jeeti: 250 cards


• Total cards for Janu: 250 cards


• Total cards for Lalli: 250 cards


• Total cards for all: 250 + 250 + 250 + 250 = 1000 cards

• Therefore, the total number of Pokemon cards that Titu, Jeeti, Janu, and Lalli have in all is 1000 cards.

• Number of rows = 456


• Number of seats in each row = 200


• Total number of seats = Number of rows * Number of seats in each row


• Total number of seats = 456 * 200 = 91200

• 91200

• Number of bags of jellybeans = 6


• Jellybeans in each bag = 24


• Total jellybeans = Number of bags * Jellybeans in each bag


• Total jellybeans = 6 * 24 = 144

• 144 jellybeans

• Number of boxes bought = 6


• Number of erasers in each box = 42

• Total number of erasers = Number of boxes * Number of erasers in each box


• Total number of erasers = 6 * 42 = 252

• Therefore, Ankit has a total of 252 erasers.

• Number of shelves = 6


• Number of books on each shelf = 8


• Total number of books = Number of shelves x Number of books on each shelf


• Total number of books = 6 x 8 = 48

• There are 6 shelves in the class.


• Each shelf has 8 books on it.


• To find the total number of books, we multiply the number of shelves by the number of books on each shelf.


• Therefore, there are a total of 48 books on the shelves in the class.

• The total number of books on the shelves is 48.

We see
3 × 10 = 30
