Guesstimate Example # 7 | How many people do you think to call Delhi Sarai Rohilla Railway Station as their primary workplace?

Q. How many people do you think to call Delhi Sarai Rohilla Railway Station as their primary workplace?

Assumptions:

No. of platforms = 5

Length of a platform = 500m

Width of a platform = 25m

Calculations:

Total width of all platforms = 5×25 = 125 =rounded to= 150

Vendors, Hawkers, and Peddlers are present every 10m on a platform

No. of Vendors, Hawkers, and Peddlers = 500/10 = 50

Since they are usually two of those together at a point we take

No. of Vendors, Hawkers, and Peddlers on a platform = 50×2 = 100

Total no. of Vendors, Hawkers and Peddlers = 100×5 = 500

Police and armed forces are present every 25m on the width of the platforms in groups of 3 people at each spot

Total no. of Police and armed forces = (150/25)x3 = 18

Station masters are 2 for each platform = 5×2 = 10

Supporting staff required is about 2 per station master = 10×2 = 20

Maintenance staff:

For platforms- 20 per platform(working in shifts) = 10×5 = 50

For Administrative Authorities- 2 per authority (working in shifts) = (10+20)x2 = 60

Total Staff working at Delhi Sarai Rohilla railway station = 500+18+10+20+50+60 = 658 =rounded to= 650people
