A. 178
B. 195
C. 204
D. 488
E. None of these
Answer: Option B
Solution(By Examveda Team)
Le the required time be x seconds.More metres, More time (Direct Proportion)
$$\eqalign{ & \therefore 0.128:25::1:x \cr & \Rightarrow 0.128x = 25 \times 1 \cr & x = \frac{{25}}{{0.128}} = \frac{{25 \times 1000}}{{128}} \cr & \Rightarrow x = 195.31 \cr} $$
∴ Required time = 195 sec (approximately)
