By calculation,
$\ \ \ \ \ \ \ \ 4356 \\ \times\ \ \ \ \ \ \ 12 \\ ----$
$\ \ \ \ \ \ 8712 \\ + 43560 \\ ----- \\ \ \ \ \ 52272$

Evaluate: $234\times 0$

  1. $234$

  2. $100$

  3. $0$

  4. $1$


Correct Option: C
Explanation:

Any number multiplied by $0$ gives $0$ itself.

$\Rightarrow 234\times 0 = 0$

Divide : $0\div 23329$

  1. $0$

  2. $1$

  3. $23329$

  4. Not defined


Correct Option: A
Explanation:

$0$ when divided by anything results as $0$.

$\therefore 0 \div 23329 = 0$
Hence, answer is $0$.

Which of the following options is correct?
Statement 1: If $7$ friends divide $76895$ coloured beads amongst themselves, then each will get $10984$ coloured beads
Statement 2: If $16$ families went on a trip and pay Rs. $216352$ in total, then each family will pay Rs. $13522$.

  1. Both statement 1 and statement 2 are true

  2. Statement 1 is true but statement-2 is false

  3. Statement-1 is false but statement-2 is true

  4. Both statement-1 and statement-2 are false


Correct Option: C
Explanation:

Statement 1-If $7$ friends divide $76895$ beads, each friend will get $(76859\div 7)$ beads i.e., $10985$ beads
So, statement 1 is false
Statement 2: Each family will pay
Rs. $(216352\div 16)=Rs.13552$

A generator consumes 2.875 litres of diesel per hour.The quantity of diesel required to run the generator for 24 hours is ______ .

  1. $45$ litres

  2. $55$ litres

  3. $72$ litres

  4. $69$ litres


Correct Option: D
Explanation:

$\Rightarrow$  Diesel consumes by generator in $1\,hour$ = $2.875\,liters.$

$\Rightarrow$  Diesel consumes by generator in $24\,hours=24\times 2.875\,liters$
$\therefore$  Diesel consumes by generator in $24\,hours=69\,liters$.
