Dear Admin,

Pls check sol of puzzle

a clock is such that it looses 4 min every day.the clock is set right on feb 25,2008 2 p.m.how many min should be added to get the right time when the clock shows 9 am on 3rd march 2008?

ans of caitanya accepted by Admin is

total no.of days between 25 FEB 2008 and 3rd MAR 2008 are 8 days(25,26,27,28,29,1,2,3 )

now total hours is 24*8=192hrs

for 1 day clock looses 4min.

so for 8 days clock looses 32min. (8x4=32)

For every 6hrs clock looses 1 min.

so total min lost until 9am of 3rd mar 2008 will be 31min.

So the time will be 1.29pm.

I think this solution is not correct.

total no.of days between 25 FEB 2008 and 3rd MAR 2008 are 8 days(25,26,27,28,29,1,2,3 )

No of days will be 7 and not 8 as calculated by Chaitanya.
day of 25th Feb should not be calculated.

Further if clock is loosing time, adjusted time should be more than actual time if qn asked is for mins to be added on feb 25,2008 2 p.m .
If time is to be adjusted at 9 am on 3rd march 2008, then time should be near 9 am on 3rd march 2008 and not near 2 PM.

Dear admin,
Pls check solution given by you

1st case all the letters are different
total no. of words of this category = 5*4*3*2*1 = 120
2nd case B comes twice and 3 others
total no. of words of this category = (4*3*2*1)*(5*4*3*2*1)/(2*1) = 240
so total words = 120+240 = 360

ans 360 is correct
but logic given seems incorrect.
as
total no. of words of this category = (4*3*2*1)*(5*4*3*2*1)/(2*1) is not equal to 240.

it should be
total no. of words of this category = 4*(5*4*3*2*1)/(2*1) = 240

Pls check the solution for puzzle

Total no. of words of 5 letters formed by letters of the word BOMBAY.
[You should use only 5 letters out of 6 letters of the word BOMBAY]

solution given is ..................
.....
(1st case all the letters are different
total no. of words of this category = 5*4*3*2*1 = 120
2nd case B comes twice and 3 others
total no. of words of this category = 5*4*3*2*1/2*1 = 60
so total words = 120+60 = 180)

I think answer should be 360
as
solution should be

1st case all the letters are different
total no. of words of this category = 5*4*3*2*1 = 120
2nd case B comes twice and 3 others
total no. of words of this category = 4*(5*4*3*2*1/2*1) = 60*4=240 because there will be 4 combinations of such words.
so total words = 120+240 = 360

pls excuse me if I am wrong.

Dear M4Maths, as specified, the unacceptable solution x = 3 in the given example is ok. But in mathematics, square root of a negative number exists. So, why is it unacceptable? On what grounds is that solution unacceptable??

1!+2!+3!+........+50! is divided by 5! then the remailnder is------------------?
a)3 b)33 c)13 d)93

all terms after 5! are fully divisible by 5!.
hence 1!+2!+3!+4! = 1+2+6+24 = 33
when 33 is divided by 5!(120), then we get 33 as remainder.

why not 7/9???????????????????????
I also didn't see any restriction that x-3 cannot be negative inside the square root.infact i expected this and i have even explained that taking 7/9, both sides will be having negative number inside the roots. ADMIN, plz check the reason i have submitted and provide me points.
