Horse started to chase dog as it relieved stable two hrs ago. And
horse started to ran with
average speed
22km/hr, horse crossed 10 mts road and two small pounds with depth
3m, and it crossed two small street with 200 mts length. After
traveling 6 hrs, 2hrs after sunset it got dog.
compute the speed of
dog?
Ans:
As we have speed and travel time of horse, we can get distance
travelled by it...
Hence d = 22*6 =
132km,
Exactly this 132km
was travelled by dog in 8 hours (as it started two hours earlier).
Hence speed of dog =
132/8 = 16.5km/hr Ans:16.5km/hr.

46.3,
22 , 7, 45, 15, ? , 31
Solution:
Here it appear simple, because it arranged in arranged in sequence
manner, but the
actual question was
some what twist mentioning fibonacci series and more over question
was in statements (no numbers).. hence first try to understand the
question well.
here let group
alternate terms 3,7,15,31 (3+4 =7, 7+8 =15, 15+16=31)
Similarly for second
group (22,45,? (22+23 = 45, 45+46 = 91) hence ans is 91.
