Puys... IIFT 2015 GK ke liye thread hai kya??
(1!)^1+(2!)^2+(3!)^3+(4!)^4+(5!)^5+.............(100!)^100. This a sum based on factorial. Plz explain the ans
abhi, bhuvan and chirag can do a work in 24, 30 and 40 days respectively. if they work in this fashion: abhi works for 1 day then bhuvan works for 2 days and chirag works for 3 days. in this manner how long will it approximately take for the work to be completed
Best Approach Please ....
P, Q , R start from the same place with a speed of a kmph , (a+b) kmph and (a+2b) kmph respectively . if Q starts p hours after P , how any hours after Q should R start, so that both Q, R overtake P at the same time , Given a>0, b>0
P and Q are two pipes that take 15 and 12 hours to fill a tank. Tap R, which is an emptying tap is fitted to the side at half of the height of tank if time taken to fill the second half is thrice that of first half, then how many hours does R take to empty a full tank
X! has 24^y as a factor where y is the highest power of 24 contained in it . How many values can X take.
Mention approach also. Thanks.
Find the remainder when (4)^32^32 is divided by 7.
Mention the approach too.Thanks.w1,w2,......,w7 are 7 positive integral value such that by attaching the coefficients of +1,0,-1 to each value available and adding the resultant values, any number from 1 to 1094 can be formed. if w1,w2.....,w7 are in ascending order, then what is the value of w3.
Approach?
If the (p+1)th, (q+1)th, (r+1)th terms of an AP are in GP when p, q, r are in HP, then the ratio of the first term to the common difference of the AP is?
Remainder when 45! Is divided with 47.
Mention the approach too. Thanks.

There are three categories of jobs A, B and C. The average salary of the students who got the job of A and B categories is 26
a) lies between 30 and 44
b)lies between 28 and 34
c)lies between 34 and 43
d)lies between 29 and 48
Can anyone share the approach to handle below type of questions:
Of three taps X, Y and Z, Y takes 2 times as much time as X and Z together, while X takes 20 minutes more than Y and Z together to fill a tank.
If the three taps together fill the tank in 24 minutes, then how long does X take to fill the tank individually?
a) 30 minutes
b) 60 minutes
c) 90 minutes
d) 120 minutes
