Yep sure
see it loses 1/2 %
it means it loses 7.2 minutes / day
So in one week total loss 50.4 min
Now gain 1/4%
it means 3.6 min/day
1 week-- 25.2 min
net loss 25.2 minutes
i.e. 25 min 12 sec
Hence tym will be 11:34:48 
and dat means my method sucks..hehe..:P
chalo yaar bye..i m going ...catch u all later...
@mickym arre bhai bahut gandi calculation kari hai maine abhi...poori week k hrs wagerah nikalkar...ghanta ssc mein attempt karta main ye...but the solution u gave was so easy...the 1st approach shud be just perfect....
Gotta go sumwhr guys catch ya later....................Meanwhile solve this
the average marks of all students who passed in a test is 65% and those who failed is 30%. if the average of all students is 50% then find what % of students passed the test?
@mickym :sirji apka posted q hai usko btake jao hw to do :
A packet of toffees is distributed in a class. A child who receives one-eighth of the total number of toffees gets five times the average number of toffees received by the remaining children in the class. What is the strength of the class?

57.11 % ???
(400/7 )
3/7 th students fail...alligations

Bhai ji....
iska 36 ans hai ....
sabne solve kar diya ye
ye wali eqn banegi
1/8 = 5*7/(8*(N-1))

Let total no students who passed =p
failed=f
(p*0.65 + f*0.3)/(p+f ) =Avg of all = 0.5
sole n get p/f=4/3
now u to just find : p/(p+f) *100

guys its thru alligation method
difficult to explain...
50% is the averge of whole class..
65-50 =15 failure
50-30 = 20 pass
ratio 4:3 = (4/7) * 100 pass
