It's also divisible by 3

Yes...didn't check that..so the answer should be all of the above.
The series can be written as
1/4(1-1/5+1/5-1/9+....+1/221-1/225).
So the answer is 224/4*225 = 56/225
Hi, could you tell me y u have divided the entire series by 4 in the above step?
Can you plz post the detailed solution if poss coz I am a bit weak in maths:( Thanks.

we have to clculte the sum of series 1/5,1/(5*9)....
bt 1-(1/5)=4/5..in all terms will get 4 numerator..
so dividing the whole expression by 4 is the sol'n.
thnx for the 1st Q..did u gt the second one???
Q wat r d last 2 digits of 14 raised to 14 raised to 14???
is Q24 talking of the perimeter of the given fig den d ans wat m gting is (26+6pi)cm...is dat d ans???if it's ryt den i'll give d detailed sol..
abhishek_techi SaysYes...didn't check that..so the answer should be all of the above.
But it's not divisible by 11 so the answer can't be all of the above

Yup your answer is correct. I'm also getting the same. The answer in the book is wrong.
Can somebody please help me in finding the answer for these q.s
Find no. of zeroes in
1. 72 ! (m getting 16, but in the book ans is givn to be 18 😞 )
2. 1! * 2 ! * 3! ......50 !

1. Divide 72 by 5 repeatedly, ignoring the remainder:
72 by 5 = 14 times
14 by 5 = 2 times
2 by 5 = 0 times
Thus, total = 16 times, i.e. 16 zeroes
2. In this, you need to find the combinations of 5 and 2, since 5*2 = 10. Once you get the number of such combinations, you'll get the number of zeroes. I only remember this idea right now, can't solve it as I've been out of practice for more than two years now 😐
1.)The answer is 16.
2) the answer is 235
Thanks for replying abhishek
Can you please explain me how did you reach the answer ?
TIA
Since, taxi 14yrs old so no deprciation & self owned so no salary issue
cost is only incurred by fuel.
For one trip fuel consumed= 7/12litre
cost=7/12*15=Rs. 35/4 for every trip
Meter reading for one trip=10+5*5+8*1=Rs.43
Total amt given by customer=1.2*43
profit=1.2*43-35/4=Rs.42.85
%profit=42.85/35/4=489%
but, isn't it Rs 10 fixed for the first ten minutes of waiting?
Then , meter reading wud be = 10 + 5*5 + 10 = 45
can anebody reply to my prev Q of finding d last 2 digits of 14 raised to 14 raised to 14???

The first part is simple.
For the second one, 1!*2!*..9! has 5 zeroes, for 5! to 9! . Then for 10! to 14! we have 2*5=10 zeroes.
For 15! to 19! we have 3*5=15 zeroes and so on.
So we get 5+10+15+20+...45+10 = 235.
The 10 is for 50!
wrong post..
Hi,
Can you please suggest some links where i can give Moc GMAT and test my scores.
I only have 13 days to go for my GMAT
nobody knows wats the last 2 digits of 14raised to 14raised to 14???
