But if the rupees were turned into fifty paise coins and the five paise coins into ten paise coins, he would lose Rs. 1.95. What sum has he?

Let him have x rupees and y 5 paisas
The initial sum is x + 0.05y
Now, if they are interchanged, the men will have 0.05x + y rupees.
therefore, 0.05x + y = x + 0.05y + 5.70 rupees
or, 0.95y - 0.95x = 5.70
or 95y - 95x = 570
or, y - x = 6
or, y = 6 + x ------ equation 1
now,
it the rupees are turned into 50 paisas and 5 paisa coins into 10 paisas,
0.5x + 0.1y = x + 0.05y -1.95
or, 0.05y - 0.5x = - 1.95
or, 5y - 50x = -195
or, y - 10x = -39 ----------equation 2
From equation 1 and 2,
(6+x) - 10x = - 39
or, 6 - 9x = -39
or, 2 - 3x = - 13
or, -3x = -15
or, 3x = 15
or, x = 5
therefore, from equation 1,
y = 6 + 5 = 11
Therefore, the sum is = 5rupees + 11X 0.05rupees = 5.55rupees
or 5 rupees and 11 five paisas.

There are no 5 paise coins in circulation in India, therefore your question does not make any sense.
