CBSE Class 2 Mathematics Revision Assignment Set 06

Question 1. In a year of 365 days, a school worked only for 220 days. Find the number of holidays during the year.
Answer: Total number of days in a year = 365
Number of working days = 220
Number of holidays = \(365 - 220 = 145\)
Number of holidays: 145
In simple words: Subtract the number of days the school was open from the total days in a year to get the holidays.

Exam Tip: Always align numbers properly by their place values (Hundreds, Tens, Ones) before subtracting.

Question 2. A designer made 155 short skirts and 268 long skirts before Christmas. How many skirts did she make in all?
Answer: Number of short skirts = 155
Number of long skirts = 268
Total number of skirts = \(155 + 268 = 423\)
Total number of skirts: 423
In simple words: Add the short skirts and long skirts together to find the total amount.

Exam Tip: Remember to carry over the extra tens and hundreds correctly when adding columns that sum to 10 or more.

Question 3. Ana has a book with 400 pages. She read 132 pages yesterday. How many pages are still to be read?
Answer: Total number of pages = 400
Pages read = 132
Pages still to be read = \(400 - 132 = 268\)
268 pages are still to be read.
In simple words: Take away the pages already read from the total page count using subtraction with borrowing.

Exam Tip: When subtracting across zeros, borrow carefully from the hundreds place through the tens place.

Question 4. Subtract 328 from 653.
Answer: Set up the subtraction problem: \(653 - 328\)
Ones place: \(13 - 8 = 5\) (after borrowing 1 ten)
Tens place: \(4 - 2 = 2\)
Hundreds place: \(6 - 3 = 3\)
Difference = 325
In simple words: Subtract the smaller number from the larger number column by column from right to left.

Exam Tip: Double-check your subtraction by adding the answer to the number you subtracted (\(325 + 328 = 653\)).

Question 5. Add 239 and 563.
Answer: Set up the addition problem: \(239 + 563\)
Ones place: \(9 + 3 = 12\) (write 2, carry over 1)
Tens place: \(3 + 6 + 1 = 10\) (write 0, carry over 1)
Hundreds place: \(2 + 5 + 1 = 8\)
Sum = 802
In simple words: Add the digits in each column starting from the ones place and carry over values as needed.

Question 7(a). 782, 234, 567, 814, 674, 427
Answer: 234, 427, 567, 674, 782, 814
In simple words: Ascending order means arranging numbers from the smallest to the largest.

Exam Tip: Compare the first digit (hundreds place) to find the smallest number first.

Answer: 600, 601, 610, 611, 616, 626
In simple words: Since all start with 60 or 61, compare tens and ones to order from smallest to largest.

Question 7(d). 205, 502, 250, 520, 255, 522
Answer: 205, 250, 255, 502, 520, 522
In simple words: Group the 200s first in ascending order, then the 500s in ascending order.

Exam Tip: Look at the tens place when the hundreds digits match.

Question 7(e). 187, 125, 101, 163, 109, 199
Answer: 101, 109, 125, 163, 187, 199
In simple words: All numbers start with 1, so compare the tens place and then the ones place to sort from smallest to largest.

Exam Tip: Between 101 and 109, 1 is less than 9, so 101 comes first.
