Directions: Read the following information to answer the question.
Two persons start, one from point A towards B and the other from B towards A. Distance between A and B is d meters. The person starting from B gives a whistle as soon as he starts and the person starting from A hears the whistle after 10 seconds of his (A) start. Speed of A and B are 2m/s and 1.5m/s respectively. Speed of sound is 330m/s.
Since A listens the whistle after 10 seconds, so both the sound of whistle
and person A both have travelled for 10 seconds, therefore the distance
travelled by A = 20 mts and that by sound = 330 × 10 = 3300 m. So the
distance d = 3320 m.
If digits of M are distinct then palindromes combinations are ruled out.
So the maximum value of N is 81 (in the combination of 81 and 198).
The coins should be put as follows: 1, 2, 4, 8, 16, 32, 64, 1, 2, 4, 8, 16, and hence he can meet all denominations.
Hence 12 bags.
