Question

The number of biscuit packets consumed by each child is given below:
Find the cost of biscuits that are consumed.

• A. $8
• B. $48
• C. $12
• D. $24

Answer 1

The correct option is D $24

Number of biscuits in 1 packet = 3
$\text{Price of each biscuit}=\$2$
Total number of biscuit packets in the table = 2 + 1 + 1 = 4

$\text{So, the total price of biscuits}=3\times \$2\times 4$
$=(3\times \$2)\times 4$

$\text{Let us find the result of}3\times \$2.$

From the multiplication table, we see:



$\text{∴ Total price of biscuits}=\$6\times 4$

Now, from the multiplication table, we see:


So, the total price of all the biscuits consumed is $24.
