Answer 2

$\red{\large\underline{\sf{Solution-1}}}$

Solution (a)

$\red{\rm :\longmapsto\:9 \times 1 = 9}$

$\red{\rm :\longmapsto\:9 \times 2 = 18}$

$\red{\rm :\longmapsto\:9 \times 3 = 27}$

$\red{\rm :\longmapsto\:9 \times 4 = 36}$

$\red{\rm :\longmapsto\:9 \times 5 = 45}$

Solution - (b)

$\green{\rm :\longmapsto\:11 \times 1 = 11}$

$\green{\rm :\longmapsto\:11 \times 2 = 22}$

$\green{\rm :\longmapsto\:11 \times 3 = 33}$

$\green{\rm :\longmapsto\:11 \times 4 = 44}$

$\green{\rm :\longmapsto\:11 \times 5 = 55}$

Solution - (c)

$\blue{\rm :\longmapsto\:21 \times 1 = 21}$

$\blue{\rm :\longmapsto\:21 \times 2 = 42}$

$\blue{\rm :\longmapsto\:21 \times 3 = 63}$

$\blue{\rm :\longmapsto\:21 \times 4 = 84}$

$\blue{\rm :\longmapsto\:21 \times 5 = 105}$

Solution - (d)

$\purple{\rm :\longmapsto\:25 \times 1 = 25}$

$\purple{\rm :\longmapsto\:25 \times 2 = 50}$

$\purple{\rm :\longmapsto\:25 \times 3 = 75}$

$\purple{\rm :\longmapsto\:25 \times 4 = 100}$

$\purple{\rm :\longmapsto\:25 \times 5 = 125}$

Solution - (e)

$\purple{\rm :\longmapsto\:50 \times 1 = 50}$

$\purple{\rm :\longmapsto\:50 \times 2 = 100}$

$\purple{\rm :\longmapsto\:50 \times 3 = 150}$

$\purple{\rm :\longmapsto\:50 \times 4 = 200}$

$\purple{\rm :\longmapsto\:50 \times 5 = 250}$

$\green{\large\underline{\sf{Solution-2}}}$

We know,

A natural number is divisible by 3 if sum of digits is divisible by 3.

Here, given number is 7209.

So, Sum of digits = 7 + 2 + 0 + 9 = 18, which is divisible by 3.

Hence, 7209 is a multiple of 3.

$\blue{\large\underline{\sf{Solution-3}}}$

9th multiple of 16

$\blue{\rm :\longmapsto\:16 \times 9 = 144}$

$\large\underline{\sf{Solution-4}}$

$\rm :\longmapsto\:7 \times 1 = 7 \: \: \: (odd)$

$\rm :\longmapsto\:7 \times 2 = 14\: \: \: (even)$

$\rm :\longmapsto\:7 \times 3 = 21\: \: \: (odd)$

$\rm :\longmapsto\:7 \times 4 = 28\: \: \: (even)$

$\pink{\large\underline{\sf{Solution-5}}}$

$\pink{\rm :\longmapsto\:10 \times 1 = 10}$

$\pink{\rm :\longmapsto\:10 \times 2 = 20}$

$\pink{\rm :\longmapsto\:10 \times 3 = 30}$

$\pink{\rm :\longmapsto\:10 \times 4 = 40}$

$\pink{\rm :\longmapsto\:10 \times 5 = 50}$

$\pink{\rm :\longmapsto\:10 \times 6 = 60}$

$\pink{\rm :\longmapsto\:10 \times 7 = 70}$

$\pink{\rm :\longmapsto\:10 \times 8 = 80}$

$\pink{\rm :\longmapsto\:10 \times 9 = 90}$

$\pink{\rm :\longmapsto\:10 \times 10 = 100}$

• All multiples are even.

$\purple{\large\underline{\sf{Solution-6}}}$

$\purple{\rm :\longmapsto\:8 \times 1 = 8}$

$\purple{\rm :\longmapsto\:8 \times 2 = 16}$

$\purple{\rm :\longmapsto\:8 \times 3 = 24}$
