Answer: Option A. -> True
:
A
The divisibility rule for a number to be divisible by 4 is that the last 2 digits of the number should be divisible by 4.
For e.g: In 1328 the last 2 digits =28, which is exactly divisible by 4.
→ 1328÷4=332, with a remainder of 0.
Hence 1328 is exactly divisible by 4.

Answer: Option A. -> 50 tens 5 ones
:
A
50 Tens 5 Ones = 50×10+5×1=500+5=505
4 Hundreds, 9 Tens9 Ones = 4×100+9×10+9×1=400+90+9=499
505>499
Hence, 50 Tens5 Ones is greater.

Answer: Option B. -> False
:
B
A number isdivisible by6if it is divisible by both 2 and 3.
In 7245: sum of the digits is = 7 + 2 + 4 + 5 = 18, which is divisible by 3.
If a number is even, it is divisible by 2.
Here 7245 is an odd number, hence it is not divisible by 2.
∴ 7245 is not divisible by 6.
