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
