@Nithya.
This is very simple just see clock at the time of 7 o'clock.
The difference between hour hand and minute is 25 min.

I think they are counting clock wise direction from hour hand to minute hand. If they count from minute hand to hour hand it will be 35 mins

Simple method:
In one hour,once minute hand and hour hand comes in straight line
so our answer is something 7 past,not 8 past
use formula,
titha(0)=30h-11/2m
titha is 180,hour hand is on 7
put values
we get titha=60/11
convert into quotitent*remainder/divisor format
we get
5*5/11
So answer is 5*5/11 past 7.

In 1 hour the min hand will gain 60 min and the hour hand will gain 5 min (i.e if the time is 5 the hour hand will take 5 min spaces to reach 6) so 60-5= 55
Did you understand this?

How do you know that at 7 the difference is 25min?
@ Nitesh: Assuming I don't have a watch to look at and count the minutes.

@Harshad
Man at 7 o clock, the hour hand is at 7 and the minute hand is in 12 i.e 60th min. assume the display in your watch is like 5 10 15.. 60.. so at 7 the hour hand will be at 35 and the min hand will be in 60.. now jus go on adding the minute space clockwise or els simple (60-35) gives 25 mins space..!!

This problem is very simple . . . .
For this problem
in clock 7 ki opposite 1 i.e 5min
hence at 5:[5/11]min past 7 O'clock at that time hands of a clock be in straight line
or
at 60/11 min past 7
the hands of a clock on straight line . . . . .

For straight line angle =180
The formula is for finding angle =30H-(11/2)*M
where H =>Hours
M => Minute.
Now
What is the formula? whether its 11/2*min-30hr or 30hr-11/2*min?

@amit:11/2min-30h this formula applicable only when h<6
if u put h=6 or above then the min>60 which is not acceptable(for the 180 degree),
in this problem if we put that formula then the ans is 77(10/11)
but in that case the h=7 so we apply the another formula which is 30h-11/2
in this case if we put that then formula the ans is 5(5/11)
if u apply that formula then u will find that min<60 which is acceptable
BASICALLY WE NEED THIS 2 FORMULAS BUT IN DIFF CASE...
hope u will understand:)
Minute hand will have to gain only 5 min. spaces.
