Question 38

1. We know that
   (1 ext{ rupee} = 100 ext{ paise}).
2. If we have (r) rupees, to change rupees into paise we multiply by (100).
   So, number of paise = (r imes 100).
3. Write the multiplication clearly:
   (r imes 100 = 100 imes r = 100r).
4. Therefore, (r ext{ rupees} = 100r ext{ paise}).

Quick check: If (r=1), we get (100 imes 1 = 100) paise (correct!). If (r=2), we get (100 imes 2 = 200) paise.
