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.

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

11 and 8
Step-by-step explanation:
x+y=19
3x=2+2y
x=19-y
3(19-y)=2+2y
57-3y=2+2y
55=5y
y=11
x=19-11
x=8
A= 8
B=11
Step-by-step explanation:
3a=2+2b
a+b= 19
a=19 - b
Substitute a= 19-b to 3a=2+2b
3(19-b)=2+2b
57-3b=2+2b
57-2=2b+3b
5b=55
b= 11
a=19 - b
a=19 - 11
a= 8

The numbers are 3 and 4.
Step-by-step explanation:
First, write a formula by allowing x to represent the first number and x+1 will be the second number. Thus, 3x + [2(x+1) + 2] = 19.
Then, 3x + 2x + 2 + 2 = 19.
Combining all the similar terms it will give: 5x + 4 = 19.
Move 4 to the right side of the equation. Thus, 5x = 19 + (-4).
Simplifying the equation it will be 5x = 15. Then divide both sides of the equation by 5 to get the value of x. 5x/5 = 15/5. Therefore, x = 3.
Find the value of the other number using equation: x+1. Thus, 3+1 = 4.
To check if the answers are correct. Replace: x with 3 and x+1 with 4. Thus, 3(3) + 2(4) + 2 = 19. 9 + 8 + 2 = 19. 19 = 19.

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
