The clock is gaining 8 min per two hours, if it is set at 10.10,then what is the correct time if it shows 4.34 on the same day.pls explain the proceedings in detail

The proper time is 4:10
The clock had changed by 6 hours and 24 minutes.
If it gains 8 minutes every 2 hours then in 6 hours it will gain 24 minutes. (2*3=6 8*3=24)
That means that it is 24 minutes ahead and that you need to subtract 24 minutes from the time shown.
Hope this helps

10:10 to noon/midnight = 1 hr + 50 minutes
Noon/midnight to 4:34 = 4 hr + 34 minutes
Add: 5 hours and 84 minutes which is the same as 6 hours and 24 minutes.
As a decimal, 24 minutes would be 24/60 or .4.
So, the time interval is 6.4 hours.
6.4/2 = 3.2 x 8 minutes = a gain of 25.6 minutes.
Add this gain to the correct time (4.34 + 25.6) = clock time of 4.59.6.

Let me convert the hours into minutes. Let x depict correct time and y depict the clock time.
120x=128y
number of minutes between the clock reaching 10.10am to 4.34pm is 384y. Using the above equation, we get 360x. So the actual time is 4.10pm
120x=128y
number of minutes between the clock reaching 10.10am to 4.34pm is 384y. Using the above equation, we get 360x. So the actual time is 4.10pm

4.34 is 16.34.
16.34-10.10=6hr24mints=>384min
this clock gains 8min every 2 hrs=>8/120=>0.066min per min,
time ahead = 0.066X384 = 253.44min =>4hrs 20 mn (approx.)
real time = time on clock -time ahead
= 4.34-4.20
=0.14 => 12.20(ans).
