Time Question

Hi, can anyone solve this question....thanx

A digital wristwatch was set accurately at 8:30 AM and then lost 2 seconds every 5 minutes. What time was indicated on the watch at 6:30 PM of the same day if the watch operated continously until that time?

(A) 5:56
(B) 5:58
(C) 6:00
(D) 6:23
(E) 6:26

8:30AM to 6:30PM is a 10 hour difference, which is 600 minutes. If the watch loses 2 seconds every 5 minutes, it will have lost 2(600/5)=240 seconds. 240 seconds is 4 minutes so the watch will read 6:26PM.
