#### Question 3.

Find the prime factorisation of 1320.

**Answer **

1320 = 2 × 2 × 2 × 3 × 5 × 11

#### Question 4.

If A = {x : x is a positive multiple of 3 less than 20} and B = {x : x is an odd prime number less than 20}, then find n(A) + n(B).

**Answer **

A = {3, 6, 9, 12, 15, 18}

B = {3, 5, 7, 11, 13, 17, 19}

n(A) = 6

n(B) = 7

∴ n(A) + n(B) = 13

**Answer **

Reduce the fraction in its simplest form.

Solution:

#### Question 6.

Simplify the following:

**Answer **

#### Question 7.

A number is divisible by 5 and 8 both. By what other numbers with that number be always divisible?

**Answer **

1, 2, 4, 10, 20, 40

#### Question 8

Arrange the fractions in ascending order.

**Answer **

#### Question 9.

Find the smallest number of 5-digits which is divisible by 12, 15 and 18.

**Answer **

12, 15 and 18

∴ LCM of given numbers = 2 × 2 × 3 × 3 × 5 = 180

Smallest number of 5-digits = 10000

We divide 10000 by 180 and find the remainder.

According to the given condition,

we need the least number of 5-digits

which is exactly divisible by 12, 15 and 18.

The required number = 10000 + (180 – 100) = 10080

#### Question 10.

Three bells are ringing continuously at intervals of 30, 40 and 45 minutes respectively. At what time will they ring together if they ring simultaneously at 5 A.M.?

**Answer **

LCM = 2 × 2× 2 × 3 × 3 × 5 = 360

After = 360 minutes

360 minutes = 6 hours

They will ring together again at 11 a.m.
