Question

You have boxes that will hold 1 candy bar, 3 candy bars, 9 candy bars,
and 27 candy bars. If each box must be packed full, what is the fewest
number of boxes you need to hold 257 candy bars?*

Answer 1

Answer:

13

Step-by-step explanation:

To minimize the number of boxes

we need to maximize the box containing 27 candy bars

By Hit and Trial

Lets take 9 boxes having 27 candies

9 * 27 = 243

The candies left are 14

We will take one box of nine candies

Left candies are 5

we will take 1 box of 3 candies and 2 box having 1 candy

Total number of boxes = 9 + 1 + 1 +2

                                      = 13
