The keys are at page 85 and the solutions as given by the members after that. If you have any specific query on the problem that has not been answered before we can take that up here. The compiling of answers require some time and I'm short of bandwidth this week.

Hi Aarav.....there was a question in QQADtest7...
Let n be a positive integer such that the product of the digits of n is 25n/8 - 211. How many values can n assume?

(1) infinitely many (2) 2 (3) 11 (4) 0 (5) 3
though i got it correct i.e., 2 by pluggin in some values n checking....what is the procedure to solve this ???

=> n is div by 8. Let n = 8k => # is 25k - 211 => k is odd.
0< 25k - 211 < 8k (as the # is > product of its digits) => k is 9 and 11.

PS 11 & 12

Let no. of tourists = t
=> 5*t = 10*4 = total no. of visits to the park
=> total no. of visits to theatre = n*6 = 8*3


2 aur 3 ke liye a little wait...abhi...pm bula raha hai


PS: junoonmba what does fecilitate mean?
