    Answer:

    • Answer of A part is 500
    • Answer of B part is 1100

    Step-by-step explanation

    We will arrange the numbers in such an order in which addition get easier so

    A = 205+196+104+95   Can be written as

         (205+95)+(104+196)

      =  300+200

      =  500

    B = 521+378+79+122 Can be written as

         (521+79)+(378+122)

      =  600+500

      =  1100

    Its very easy
