Question
Determine the sum by suitable rearrangements:
2359 + 1000 + 2641 + 9999
2359 + 1000 + 2641 + 9999
✓
Answer
2359 + 10001 + 2641 + 9999
Therefore, 59 + 41 = 100
And, 99 + 01 = 100
Therefore, (2359 + 2641) + (10001 + 9999)
= (5000) + (20000)
= 25000
Therefore, 59 + 41 = 100
And, 99 + 01 = 100
Therefore, (2359 + 2641) + (10001 + 9999)
= (5000) + (20000)
= 25000
