Question

Each cabin has 45 water bottles. How many bottles will be in 6 such cabins?

• A. $270\text{bottles}$
• B. $265\text{bottles}$
• C. $260\text{bottles}$
• D. $275\text{bottles}$

Answer 1

The correct option is A $270\text{bottles}$

Let us find the total number of bottles.
$\bullet$ Bottles in a cabin $=45$
$\bullet$ Number of cabins $=6$
Total number of water bottles $=\text{Bottles in cabin}\times \text{Number of cabins}$
$=45\times 6$
$\bullet$ $45\times 6$ means 6 lots of 45. We know that $45=40+5$.
$\bullet$ Hence, 6 lots of 45 means 6 lots of 40 and 6 lots of 5.

Let us represent this using rods and blocks.

$\bullet$ There will be 270 water bottles in 6 cabins.

Hence, option B is the correct answer.
