A202

B201

C188

D189

Answer:

C. 188

Read Explanation:

Sum of five numbers = 655

Average of five numbers = 655/5 = 131

Average of the first two numbers = 78

Sum of the first two numbers=78×2=156= 78 \times2=156

Third number = 123

Sum of first three numbers = 156 + 123 = 279

Sum of the remaining two numbers = 655 - 279 = 376

Average of the remaining two numbers = 376/2 = 188
