Options:
(A) 12400
(B) 12800
(C) 12970
(D) 13015
(E) 16000
a: Stream of consciousness: 12
12 × 4 + 2 = 50
50 × 4 + 2 = 202

Options:
(A) 42
(B) 43
(C) 44
(D) 45
(E) 46
answer: Stream of consciousness: Speed = 81 * 5/18 = 45/2 m/sec
Total distance covered = 650 + 340 = 990 m
Required time = 990 * 2/45 = 44 se The answer is (C).
