The average of 100 numbers is 44. The average of these 100 numbers and four other new numbers is 50. The average of four new numbers will be :
[A]24
[B]176
[C]200
[D]800

200
Sum of four new numbers = 50 \times 104 – 100 \times 44
= 5200 – 4400 = 800
∴ Average = \frac{800}{4} = 200
Hence option [C] is correct answer.
