Question no – (3)

Solution :

As we Know, 3 meter means 300 cm

300 cm cut it into 50 cm prices.

Here 300 is exactly divisible by 50.

It means ribbon cut into 6 equal 50 cm pieces.

Therefore, nothing is left in this ribbon.

Question no – (4)

Solution :

As we all Know, 3 meter means 300 cm

1 piece of ribbon is 40 cm

Needed of 8 piece of ribbon means that

40 cm × 8 = 320 cm

320 cm ribbon needed for 8 equal pieces each of 40 cm.

So, ribbon is shorter by = needed ribbon–3 meter long ribbon

Ribbon is shorter by = 320 cm – 300 cm

Ribbon is shorter by = 20 cm

Hence, 20 centimetres shorter is the ribbon than the length need.

Problem Set 34 :

Question no – (1)

Solution :

We know, A number which has only two factors, 1 and the number itself, is called a Prime Number.

2 has only two factors, 1 and 2 hence it is a prime number.

3 has only two factors, 1 and 3 hence it is a prime number.

5 has only two factors, 1 and 5 hence it is a prime number.

7 has only two factors, 1 and 7 hence it is a prime number.

17 has only two factors, 1 and 17 hence it is a prime number.

19 has only two factors, 1 and 19 hence it is a prime number.

Prime numbers between 1 and 20 are 2, 3, 5, 7, 11, 13, 17, and 19.

Question no – (2)

Solution :

As we know, a number which has more than two factors is called a Composite Number.

22 has more than two factors are 1, 2, 11, 22

48 has more than two factors are 1, 2, 3, 4, 6, 8, 12, 16, 24, 48

49 has more than two factors are 1, 7, 49

So, above number are composite number because above number has multiple factors

Composite numbers between 21 and 50 are  22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, and 49.

• 97 has only two factors, 1 and 97 hence it is a prime number.

Question no – (4)

Solution :

As we know, 2 is a even number

2 has only two factors, 1 and 2 hence it is a prime number

No other even number has only two factors

So, 2 is a prime number which is even number.

(5) 5, 7

Factors of 5 are 1,5

Factors of 7 are 1,7

Numbers which have only 1 as a common factor are called co-prime numbers

Here 1 is only one common factors

Hence, 5, 7 pair is co-prime numbers

(6) 15, 16

Factors of 15 are 1,3,5,15

Factors of 16 are 1,2,4,8,16

Numbers which have only 1 as a common factor are called co-prime numbers

Here 1 is only one common factors

So, 15,16 pair is co-prime numbers.

(7) 50, 52

Factors of 50 are 1,2,5,10,25,50

Factors of 52 are 1,2,4,13,26,52

Numbers which have only 1 as a common factor are called co-prime numbers

Here 1 and 2 are two common factors

Thus, 50,52 pair is not co-prime numbers.

(8) 17, 18

Factors of 17 are 1,17

Factors of 18 are 1,2,3,6,9,18

Numbers which have only 1 as a common factor are called co-prime numbers

Here 1 is only one common factors

Therefore, 17,18 pair is co-prime numbers.
