A man takes 6 hours 15 minutes in walking a distance and riding back to the starting place. He could walk both ways in 7 hours 45 minutes. The time taken by him to ride both ways, is
[ "7 hours 45 minutes", "4 hours 75 minutes", "4 hours 95 minutes", "4 hours 45 minutes" ]
D
Explanation: Time taken in walking both ways = 7 hours 45 minutes --------(i) Time taken in walking one way and riding back= 6 hours 15 minutes-------(ii) By equation (ii)*2 -(i), we have Time taken to man ride both ways, = 12 hours 30 minutes - 7 hours 45 minutes = 4 hours 45 minutes Answer: C) 4 hours 45 minutes

For any integer k greater than 1, the symbol k* denotes the product of all integers between 1 and k, inclusive. If k* is a multiple of 945 what is the least possible value of k?
[ "11", "9", "13", "7" ]
B
945 = 3*3*3*5*7 Thus k must include numbers at least up to the number 9 so that there are at least three appearances of 3 (that is: 3, 6, and 9). The answer is C.
