CBSE Class 3 Mathematics NCERT Solutions: Chapter 3 Give and Take

(a) To find 10 less than 34, we subtract 10 from 34: $34\; -\; 10\; =\; 24$.

(b) To calculate 53 minus 20, we subtract the numbers: $53\; -\; 20\; =\; 33$.

(c) To find 11 more than 31, we add 11 to 31: $31\; +\; 11\; =\; 42$.

(d) To find 11 less than 66, we subtract 11 from 66: $66\; -\; 11\; =\; 55$.

(e) To calculate 62 plus 13, we add the numbers: $62\; +\; 13\; =\; 75$.

(f) To find 23 less than 89, we subtract 23 from 89: $89\; -\; 23\; =\; 66$.

(g) '10 and 40 more' means adding 10 and 40: $10\; +\; 40\; =\; 50$.

(h) '9 added to 28' means finding the sum of 9 and 28: $28\; +\; 9\; =\; 37$.

(i) The sum of 9 and 44 is found by adding them: $9\; +\; 44\; =\; 53$.

(j) 'Reducing 98 by 34' means subtracting 34 from 98: $98\; -\; 34\; =\; 64$.

(k) '4 and 37 more' means adding 4 and 37: $4\; +\; 37\; =\; 41$.

(l) 'Take 35 away from 83' means subtracting 35 from 83: $83\; -\; 35\; =\; 48$.

To find the total number of candles Rafi has, we need to add the initial number of candles to the number of candles he received.

Initial candles = 153

Candles received = 237

We can add these using column addition: 153 + 237

-----

Adding the ones column: 3 + 7 = 10. Write down 0 and carry over 1 to the tens column.

Adding the tens column: 5 + 3 + 1 (carry-over) = 9. Write down 9.

Adding the hundreds column: 1 + 2 = 3. Write down 3.

So, the total number of candles is 390.

Answer: Rafi has 390 candles now.

To find the total number of people in both compartments, we add the number of people in each compartment.

People in the first compartment = 132

People in the second compartment = 129

We use column addition: 132 + 129

-----

Add the ones: 2 + 9 = 11. Write down 1 and carry over 1 to the tens place.

Add the tens: 3 + 2 + 1 (carry-over) = 6. Write down 6.

Add the hundreds: 1 + 1 = 2. Write down 2.

The total number of people is 261.

Answer: There are 261 people in all in both compartments.

To find the total number of pebbles, we add the number of pebbles Shanu found and the number of pebbles Karim found.

Shanu's pebbles = 138

Karim's pebbles = 44

We perform column addition: 138 + 44

-----

Add the ones: 8 + 4 = 12. Write down 2 and carry over 1 to the tens place.

Add the tens: 3 + 4 + 1 (carry-over) = 8. Write down 8.

Add the hundreds: 1 + 0 = 1. Write down 1.

The total number of pebbles is 182.

Answer: They found 182 pebbles in all.

First, we complete the table by adding the numbers in each row and column.

Completed Table:

Now, let's answer the questions:

(a) How many students in the school like oranges?

We add the number of girls who like oranges and the number of boys who like oranges: 136 + 128 = 264.

(b) How many students in the school like mangoes?

We add the number of girls who like mangoes and the number of boys who like mangoes: 240 + 243 = 483.

(c) Altogether, how many students are there in the school?

We add the total number of girls and the total number of boys: 376 + 371 = 747. Alternatively, we can add the total students who like oranges and the total students who like mangoes: 264 + 483 = 747.

(d) Is the number of girls more than 350 or less than 350?

The total number of girls is 376. Since 376 is greater than 350, the number of girls is more than 350.
