Step-by-step explanation:

Let's solve each part step by step:

(i) Capacities of ten different vessels which can be filled completely by mug-A with exact number of times

Mug-A has a capacity of 50 ml. The capacities of vessels that can be filled completely by mug-A are multiples of 50 ml. The first ten such capacities are:

50

×

1

=

50

50×1=50 ml

50

×

2

=

100

50×2=100 ml

50

3

=

150

50×3=150 ml

4

=

200

50×4=200 ml

50

5

=

250

50×5=250 ml

×

6

=

300

50×6=300 ml

50

×

7

=

350

50×7=350 ml

8

=

400

50×8=400 ml

50

9

=

450

50×9=450 ml

10

=

500

50×10=500 ml

(ii) Capacities of ten different vessels which can be filled completely by mug-B with exact number of times

Mug-B has a capacity of 100 ml. The capacities of vessels that can be filled completely by mug-B are multiples of 100 ml. The first ten such capacities are:

100

×

1

=

100

100×1=100 ml

100×8=800 ml

100

900

100×9=900 ml

100

10

=

1000

100×10=1000 ml

(iii) Common capacities of vessels which can be filled completely by mugs A as well as B with exact number of times

The common capacities will be the least common multiples (LCM) of 50 ml and 100 ml, and multiples thereof. Since 100 is a multiple of 50, the LCM is 100 ml. Thus, the common capacities are multiples of 100 ml. The first ten such capacities are:

100 ml

200 ml

300 ml

400 ml

500 ml

600 ml

700 ml

800 ml

900 ml

1000 ml

(iv) The least capacity of a vessel which can be filled completely by mugs A as well as B with exact number of times

As discussed in part (iii), the least capacity is the LCM of 50 ml and 100 ml, which is:

LCM

(

50

 ml

,

100

 ml

)

=

100

 ml

LCM(50 ml,100 ml)=100 ml

So, the least capacity of a vessel that can be filled completely by both mugs A and B is 100 ml.
