ii)250

iii) infinite

iv) You can also call it the test of divisibility for 12. A number is divisible by 12 if the number formed by the last two digits in the number is divisible by 4 AND the sum of the digits in the number is divisible by 3. For example, for 123,456 the last two digits (56) is divisible by 4, AND 1 + 2 + 3 + 4 + 5 + 6 = 21.

v) What is 35/75 Simplified? - 7/15 is the simplified fraction for 35/75.

vi) The speed of train is 60 km/hr; find its speed in metres per second.

Solution:

According to the problem, we know the speed of the train is 60 km/hr.

Distance covered in metres;

1 km = 1000 m

Therefore, 60 km = 60 × 1000 m

60 km = 60000 m

Time taken in seconds;

1 hr = 60 minutes;

1 minutes = 60 seconds

Therefore, 1 hr = 60 × 60 sec

1 hr = 3600 sec

Speed = (Distance )/(Time )

= 60000/3600 metres per second

To find Speed when Distance and Time are given

= 16 2/3 metres per second

vii) 3

viii) -4

x) 60°+120° = 180°

xi) false

xii) If two circles are equal, then their centre and circumference will coincide and hence, the radii will also be equal. (

xiii)True.

xiv) It is given that AB and XY are two terminated lines and both are equal to a third line PQ. Euclid's first axiom states that things which are equal to the same thing are equal to one another
