Correct option is B
Solution:
4 + 44 + 444 + 4444 + 44444
Simplify each term individually:
4 = 4
44 = 40 + 4
444 = 400 + 40 + 4
4444 = 4000 + 400 + 40 + 4
44444 = 40000 + 4000 + 400 + 40 + 4
Now, summing them all together:
4 + (40 + 4) + (400 + 40 + 4) + (4000 + 400 + 40 + 4) + (40000 + 4000 + 400 + 40 + 4)
Therefore, the sum is: 49380
