x = 10/y
x - 0.05 = 10/1.25y
---
x - 0.05 = 10/1.25y
10/y - 0.05 = 10/1.25y
10/y - 10/1.25y = 0.05
10*1.25/1.25y - 10/1.25y = 0.05
10( 1.25/1.25y - 1.00/1.25y ) = 0.05
10( 0.25/1.25y ) = 0.05
2.5/1.25y = 0.05
2/y = 0.05
y = 2/0.05
y = 40
---
x = 10/y
x = 10/40
x = 0.25
---
answer:
the number of persons is 40
each received 0.25 rupee
