Correct Answer: 322
Solution :
Vacant berth in train B = (200 – 190) + (200 – 183) + (400 – 348) + (300 – 215) + (500 – 414)
= 10 + 17 + 52 + 85 + 86 = 250
Vacant berth in train C = (200 – 198) + (200 – 191) + (400 – 364) + (300 – 291) + (500 – 484)
= 2 + 9 + 36 + 9 + 16 = 72
Vacant berth in trains B and C = 250 + 72 = 322
Hence, the correct answer is 322.
