1) 16 - (x)² - (y)² + 2xy
   = (4)² - (x² + y² - 2xy)
   = (4)² - (x- y)²
   = (4 + x - y) [4 - (x - y)]
   = 
(4 + x - y) (4 - x + y)
2) Let the Principle be Rs x.
    S. I. = PRT / 100
           = (x * 5 * 3) / 100
           = 15x / 100
           = 3x / 20
Amount = Principle + S. I.
   410    = x + (3x / 20)
   410    = 20x / 20 + 3x / 20
   410    =  23x / 20
410 * 20 = 23x
8200 = 23x
x = 8200 / 23
x = Rs 356.52
