Question

Rajat has five school bags, which he collected from his classmates, and marked them from 1 to 5.


Each school bag contains notebooks. Bag 1 has two notebooks, Bag 2 has four notebooks, and Bag 3 has eight notebooks. Observe the pattern in which the number of notebooks are arranged in the five bags, and find the total number of notebooks.

• A. 32
• B. 30
• C. 62
• D. 60

Answer 1

The correct option is C 62

Rajat has marked the five bags from 1 to 5.

$\Rightarrow$ Number of notebooks in Bag 1 = 2
$\Rightarrow$ Number of notebooks in Bag 2 = 4
$\Rightarrow$ Number of notebooks in Bag 3 = 8


From the above pattern, we can observe that the next bag has twice the number of notebooks from the last bag.

Therefore, the number of notebooks in Bag 4 = 2 × number of notebooks in Bag 3

Number of notebooks in Bag 4 = 8 × 2 = 16 Similarly, number of notebooks in Bag 5 = 16 × 2 = 32

So, the total number of notebooks in all five bags = 2 + 4 + 8 + 16 + 32 = 62

Hence, the total number of notebooks is 62.
