Question

the students of a school decided to beautify the school on Annual Day by fixing colourful flags on the straight passage of the school they have 27 flags to be fixed at intervals of every 2 metre the flags are stored the position of the middle most flag Ruchi was given the responsibility of placing the flags Ruchi kept her books were the flags was stored she could carry only one flag at a time how much distance did she cover in completing this job and returning back to collect their books what is the maximum distance travelled carrying a flag..​

Answer 1

Answer:

As the total number of flags is 27, so there would be 13 flags on one side, 13 flags on the other side and one flag in the middle.

Consider that she fixes 13 flags on one side of the middle flag.

So, the distance covered by Ruchi to fix the first flag and return is 2m+2m=4m.

The distance covered by Ruchi to fix the second flag and return is 4m+4m=8m.

Similarly, the distance covered by Ruchi to fix the thirteenth flag and return is 4m+8m+12m⋯+13terms.

It will form an arithmetic series,

4m+8m+12m⋯+13terms

=

13

[2(4)+(13−1)4]

=
