1.99 + 2.98 + 3.97 + ..... + 49.51 + 50.50

= 1..99 + 2.(99 - 1) + 3.(99 - 2) + ..... + 49.(99 - 48) + 50.(99 - 49)

= 1.99 + 2.99 - 1.2 + 3.99 - 2.3 + ........ + 49.99 - 48.49 + 50.99 - 49.50

= (1.99 + 2.99 + 3.99 + ..... + 49.99 + 50.99) - ( 1.2 + 2.3 + ........ + 49.50)

= 99(1 + 2 + 3 + ..... + 50) - ( 1.2 + 2.3 + ........ + 49.50)
