3)7:20

x+5x=60 * 4 

x=40 5x=200 

4:00 + 200 min =7:20

Answer 2

4 hours difference is present between 4 o clock to 8 o clock.

so, 4 hours means 240 minutes.

time ration given from 4 o click to now and now to 8 o clock is  5:1

so, 4 o click to now = (5 * 240)/ 6 = 200 minutes.

and from now to 8 o clock = (1 * 240) / 6 = 40 minutes.

so current time is = 8 o clock - 40 minutes = 4 o clock + 200 minutes = 7 : 20 .
