Yes Bindu, You are right and thanks for correcting me.

and the right answer is 35 minutes.
Please find the logic and the program below:


int ppl , time , i , sum = 0;

printf("Enter the number of ppl u want to spread \r\n");
scanf("%d",&ppl);

while(sum<ppl)
{
sum = pow(3,i);
time = 5 * i;
i++;
}
printf("time in min required is %d \r\n",time);

[
out put:
Enter the number of ppl u want to spread
768
time in min required is 35
]
==================
For your refernce :
1->2 [ total 3 ppl ] took 5 min;
3 -> 6 [ total 9 ppl ] took 10 min
9 ->18 [ total 27 ppl ] took 15 min ..
27 -> 54 [ total 81 ppl ] took 20 min
81 -> 162 [ total 243 ppl ] took 25 min
243 -> 486 [ total 729 ppl ] took 30 min
729 -> 1458 [ total 2187 ppl ] took 35 min

overall it's power of 3
