Question

A carton can hold 41 packets of biscuits. Each packet has 12 biscuits.

So, a total of biscuits are packed in the carton.

• A. 486
• B. 492
• C. 474

Answer 1

The correct option is B 492

Number of biscuit packets in each carton = 41

Number of biscuits in 1 packet = 12

∴ Total number of biscuits will be =
$41\times 12$

Let us solve this using partitioning method.

The expanded form of (41 × 12) is:

Let's draw a table and write 40 and 1 on top of the second and third column and 10 and 2 in the first column of the second and third rows.

Now, we fill the table by multiplying the numbers in the corresponding rows and columns.

Finally, we add all the products to get the final answer:
$400+80+10+2=492$


Hence, there are 492 biscuits in the carton.
