At 6'o clock ticks 6 times means 5 interval
and also given that time b/w first and last tick is 30 sec.
so
30/5=6
i.e time of each interval is 6 sec.
Similarly at 12'o clock, clock ticks 12 times i.e 11 interval
so
1 interval time=6
so 11 interval=11*6
Answer=66 secpawan

Find the total number of rectangles (include squares also as rectangles) in a 8 * 8 standard chessboard?
Amit Garg
- Feb 13th, 2015
Answer is = 204.
Here is the logic
single box= 8x8
double boxes=7x7
three boxes =6x6 ....
and so on till eight boxes = 1x1 = 1
so 64+49+36+25+16+9+4+1 = 204 -
a box contains 12 marbles of three colors – green, yellow & blue – 4 each. If you were to close your eyes & pick it up, how many marbles must you take out to be sure that there are at least 2 of one colour among the marbles picked out.(SakDevi-73).Try with 20 marbles also.

Since there are only 3 colors the no of marbles needed to make any two same color is 4.Among the 4 marbles two of them will be the same color.

. two trains of length 1/6 miles are moving towardeach other with a speed of 60 miles per hour.aproaching toward each other In how much timethey will cover each other.ans.10 secPLEASE TELL THE APPROACH FOR TIS
atreya
- Aug 28th, 2012
Total dist travelled=(1/6+1/6)=1/3miles
relative speed=(60+60)=120miles per hour
therefore,
time=dist/speed
=(1/3)/120=(1/360)hours=10secs(1hr=3600secs).tmhasan7
- Sep 25th, 2006
1. Its obvious that since the trains travel towards each other the speed is 60+60 miles/hr2. The two trains will take 2/6 miles to cross themselves, since the length of the train is 1/6 miles.3. If it...

Its not the n+1th fibonacci no., the ans is nth fibanacci no.
for eg:-
if no of steps is 3 then n=3
if no of steps is 4 then n=5
if no of steps is 5 then n=8
for 6 n=13
for 7 n=21
for 8 n=34 and so on...Aravindan

There are 3 persons sitting with the right hand of Ramesh
assume Ramesh=4
a=3
b=2
c=1
Ramesh gives 1 rs/- to a he has 3 left
now a has 4 and gives 2 to b remaining a has 2
now b has 4 and gives 3 to c remaining b has 1
now c has 4 and gives 4 to Ramesh and remaining c has 0.

The answer is he is a visitor i.e. he is telling the truth
Reason:
If he was a native i.e. a liar then his answer would would have been "she says she is a native" for both cases because
If she was visitor: she would have said she is a visitor and he would have lied that she is a native
If she was native: she would have lied and again say that she is a visitor and he would have lied that she is a native.

The answer may be native, because without asking her the salesman said the answer, he says only in the condition when he is a liar, so liar means native
