A man is 20 mins late to the office if he walks at 20 kmph, and 15 mins earlier if he walks at 30 kmph. How much time will he be early/late if he walks at 25 kmph?	Pick.
A) early 1 min  B) early 2 min  C) late 1 min  D) late 2 min  E) none
let distance be x,then   time1= x/20*60,   t2=x/30*60   difference b/w both time is 35min then   x/20-x/30=35 so x=35   now for 25kmph    35/25*60= 
<gadget id="calculator"> 35/25*60</gadget>
<output>84</output>
84 min   for 20kmph time=105 min   for 30kmph time= 70min   in 30 kmph he is early by 15 min then actual time is 85 min   so the anser is he is early by 1 min   ans=early 1 min   t=35/25*60   early 1 minNSWER:early 1 min
